The total number of Boeing 787 produced. Features of business class accommodation

Those wishing to travel in comfort should choose a flight on the Boeing 787-900: the super cabin of the model will impress. Development of the airliner began when the company noticed that its main competitor, Airbus, was gaining ground. As a result, the Boeing 787 Dreamliner was released: the developers embodied the achievements of modern aircraft manufacturing in the design. Knowing how to choose your seats will make your flight a pleasure.

History of the Boeing 787-900

In the late 90s, Boeing Commercial Airplanes management noted that a new development from Airbus made their products uncompetitive. In 2001, the creation of the Sonic Cruiser model began: the airliner was supposed to fly at speeds close to supersonic. But the events of September 11 and rising oil prices forced us to reconsider our priorities. In the new conditions, aircraft were required to be economical in fuel consumption and safety, not speed. For these reasons, developments were used to create an airliner that corresponds to the changed realities civil aviation.

Presentation of the Boeing 787 900 model

The project, originally called 7E7, was unveiled in 2004, and the first airliner went on a test flight in 2011. But in 2013, the operation of the Dreamliner model was suspended as the airliners made emergency landings. In one case, lithium-ion batteries caught fire: the crew of 8 people and 129 passengers were not injured, but the situation became the basis for additional proceedings. In the same year, the causes of the problems were clarified, and operation resumed.

Features of the model and differences from its predecessors

The airliner is a jet-type passenger aircraft, with a wide fuselage and 2 engines. Its design has increased the use of composite materials: the company claims that they account for 50% of the total weight. In this case, the share of aluminum is 20%, titanium - 15%, steel - 10%.

How the Boeing 787-900 interior was changed

Capacity depends on the seating arrangement, but for a single-class configuration it is 250-330 passengers. In practice, the Boeing 787-900 uses a cabin layout that implies a figure of 234 people seated in 3 service classes.

The cabin width reaches 550 cm, which is 38 cm more than in the competitor's aircraft - the Airbus A330. As a result, the aisles became more spacious and the seats more comfortable. When placing seats according to the 3-3-3 pattern, the seat width in the “economy” is 44.4 cm. If there are 8 seats in a row, arranged according to the 2-4-2 principle, then the figure reaches 48 cm.

What does economy class look like on a Boeing 787-900?

Differences from other Boeing models are also visible in the design of the toilets. There is a movable partition between the booths, which is removed when necessary. As a result, room parameters are increased, allowing people with special physical needs to use the restroom without any problems.

The windows will appeal to those who like to watch the views: the dimensions of the openings reach 27x47 cm, which is larger than those of other civil aviation airliners. A similar result was achieved through the use of composite materials. Instead of plastic curtains, “smart glass” is used: it changes properties depending on external conditions. As a result, passengers choose from 5 lighting levels.

How is the cockpit different?

The Fly-by-wire system used is the same as on the 777. Many controls are unchanged, allowing pilots to handle different types of aircraft without retraining.

The advantages of the Dreamliner include the presence of projection indicators: devices that display information on the windshield. Also available to the crew are electronic flight plans, which can be seen on 2 screens (one for the pilot). The computer displays the information necessary to control the vessel. The aircraft is also equipped with installations for real-time diagnostics: sensors take instrument readings and transmit them to the ground. The measure allows us to reduce the time required to service aircraft.

Design Features

For increased passenger comfort, a system of sensors installed in the bow of the vessel is provided. Thanks to their work, it is possible to reduce the manifestations of turbulence.

The climate control system also deserves attention. If in predecessors the air was taken in from the engine area, passed through filters, cooled and entered the cabin, then on the Dreamliner it comes from the external environment and is subjected to appropriate processing. As a result, the problem of insufficient humidity is solved.

Thanks to the engine features, cabin noise is reduced by 40% compared to previous models.

Features of choosing places: the best and worst options

The Boeing 787 Dreamliner offers comfort, but to get the most out of your flight, choose your seats in advance. Typically, there are 3 classes of service in the cabin: “business”, “premium economy” and “economy”, with each compartment having the best and worst seating options.

In business class

When using the Boeing 787-900 scheme shown in the figure, rows 1-8 belong to business class:

• the chairs can be reclined 180˚ and you can relax as if you were on a bed;
• There is enough legroom even for tall people;
• The seats are arranged in a 2-2-2 configuration, which allows you to get up to go to the toilet or stretch your legs without disturbing anyone.

The capacity of the business compartment with the seats arranged according to this arrangement is 48 passengers.

Despite the advantages, some places in the sector also have disadvantages. The 1st, 5th and 6th rows are located near the restrooms, so passengers scurry past them. Undesirable options also include 4A and 4L: there are no windows nearby.

In premium economy

If you are not satisfied with either the “business” prices or the “economy” conditions, choose an intermediate option. When you are in Premium Economy, which seats 88 passengers, you will enjoy the following benefits:

• availability of additional legroom;
• seat dimensions are 88.9 cm in length and 43.9 cm in width;
• Possibility to set the backrest in one of 4 positions.

Look for cheap tickets for any type of transport without leaving your home:

As for the choice of seats, passengers try to reserve the 16th row. It is located near the partition separating “premium economy” from “business”, which provides legroom. There are some downsides: passengers traveling with children often sit in this row.

The worst seats on the Boeing 787-900 are located in row 24 because it is near the toilet.

In economy class

If you have purchased tickets in economy class, you will find yourself in a section with a capacity of 116 people. The seat length here is 81.3 cm and the width is 43.9 cm; The backrest can be reclined and locked in one of 3 positions.

The best seats include the 27th row, except for A and L, near which there are no portholes. But you will get additional legroom, which is important for tall passengers. Disadvantages include the proximity of restrooms.

What places should you avoid? These include the entire 40th and 41st rows, located near the toilets. Rack space for luggage may also be limited. You should not sit on 38A or 38L: they are located near the wall of the cabin, but there is no window nearby.

The nuances of choosing seats on British Airways

Flight seat locations British Airways differs from the classic scheme:

• The first class is represented by 2 rows in the bow. The seats are comfortable: you have spacious compartments, large-diameter monitors and increased attention from the staff. The compartment is designed for 8 passengers.
• World Business Class, which accommodates 42 people, is divided into 2 parts: 14 and 28 seats. The seats are arranged in a 2-3-2 pattern, and all seats are comfortable. An exception may be the 7th and 10th rows, since they are located next to the toilets and kitchen.
• The improved economy version is represented by 39 seats arranged in a 2-3-2 pattern (in the 21st row - 2-0-2). Seats with the letter E are considered not the most comfortable: you won’t be able to get up to go to the toilet without disturbing your neighbor. Also, do not sit in 20D, 20E, 20F and all the seats in the 21st row, because they are located next to the restroom.
• In the Economy sector, choose seats in row 30 for extra legroom. Is it true, hand luggage do not place it on the floor, because blocking the passages near emergency exits is not allowed. Bad places include the 43rd and 44th rows, located near the toilets. It’s not very convenient on 41A and 41 K either, since there is no porthole nearby.

The interior layout varies depending on the carrier, so reading the descriptions may not be enough. If necessary, contact the company representatives and ask questions regarding the location of the seats to save yourself from unpleasant surprises.

Features of the Boeing 787-900 cabin layout at KLM

When flying on a KLM airliner, please pay attention to the following:

• The World Business Class compartment is located in the bow, occupying 8 rows. There is plenty of legroom, with a 107cm pitch between the herringbone seats. While all passengers are comfortable, seats 1A, 1K, 2D and 2G are close to the galley and toilets, which can be a concern. Bad options 5A and 5K are also considered, since there are no portholes nearby. Otherwise, the amenities are not satisfactory: the seats can be reclined 180˚ and you can fully relax.
• “Economy class with increased comfort” is designed for 48 passengers. If legroom is a deciding factor, buy tickets for row 10 seats. Disadvantages include the proximity of the kitchen and restrooms.
• “Economy”, designed for 216 people, is divided into 2 parts. Passengers in row 30 will have the most legroom, although the proximity of the toilet will spoil the journey. It is undesirable to be located at 30A and 30K: there are no portholes next to them. Also note that due to the lack of a front row, the pull-out tables are mounted on the armrests. As a result, they cannot be lowered all the way, and the width of the chair is reduced. Unlucky seats include the entire 43rd (except 43E) and 44th row: the proximity of the bathroom and the location in the rear have an effect, as a result of which turbulence is felt more strongly.

Pay attention to the details and you won't have to deal with any unpleasant surprises!

First Class on the Boeing 787-900 Dreamliner: Passenger Experience

Josh Cahill, who traveled with British Airways from London to Beijing, shares his experience. He purchased a ticket for seat 1A, located in the premium section. What did Josh say about the flight?

“The journey began at Terminal 5 of London Airport. There was no line at registration, and the security service completed the inspection in 10 minutes. Then I went to the lounge area, where I rested and had a snack before the flight. The food was mediocre, but I liked the champagne.

When we boarded, I thought that I had been mistakenly assigned to the “business” sector. If you compare the conditions with offers from Emirates or Lufthansa, neither the service, nor the interior design, nor the comfort can withstand the competition.

What I saw on board did not surprise me: comfortable seats, the presence of USB ports and sockets are the norm, not the exception. The lack of Wi-Fi was disappointing, but the company plans to introduce it on aircraft only next year. In addition, the film that was shown to the passengers did not interest me, so the flight was a bit boring.

Breakfast and dinner left a mixed impression: on the one hand, I liked the food, as did the wine. On the other hand, they didn’t bring me a hot towel.

What deserves praise? The bedding was comfortable, especially the pajamas. But the chair seemed a little narrow: I have already said that its design requires improvement. But the service was not satisfactory, because the flight attendants were attentive and friendly.

Overall, I was pleased with the flight, although I was left with the impression that I was flying on a “business” trip. Inexperienced travelers will like this option, but if you know in practice what great service is, then this will not impress you.”

Boeing 787 Dreamliner- a family of wide-body long-haul airliners developed by Boeing in the early 2000s. The first commercial airliner with a radically increased proportion of composite materials in the structure. In addition, the aircraft is equipped with many new systems and elements that have significantly improved its flight and economic characteristics.

Story

In the late 1990s, while Boeing was actively promoting its newest jet, the Model 777, its two other wide-body jets were no longer industry leaders. The Boeing 747 and Boeing 767 quickly became outdated and required either deep modernization or complete replacement. Both of these concepts began implementation in the early 2000s. The flagship of the line had to undergo modernization under the 747X program. The Boeing 767 was supposed to retire, giving way to a completely new and first-of-its-kind transonic airliner, the Sonic Cruiser. With similar capacity figures, the new aircraft was supposed to fly at speeds of about 1100 km/h, without breaking the sound barrier, but still significantly faster than its counterparts. The Boeing 747X project was implemented very slowly, most airlines were satisfied with the old 747-400 model, and Many expected the European A380 as a new airliner. There was great interest in the Sonic Cruiser, which promised great benefits for operators.

However, the events of the early 21st century did not allow the project to flourish. After the terrorist attacks of September 11, 2001, the air transportation market contracted, and the price of oil, and therefore aviation fuel, rose sharply. The speed characteristics of the airliners were no longer so important in comparison with the characteristics of their fuel consumption. The Sonic Cruiser flew much faster, but its fairly high fuel consumption killed it. In 2002, the project was officially closed. However, many developments and technologies were not forgotten: literally a month later, in 2003, Boeing announced the 7E7 program. The project involved the creation of a classic modern aircraft, but using Sonic Cruiser technologies. The idea of ​​the new project was to create a long-range and very economical small airliner that would allow flying to small airports without working with hubs. In fact, it was a continuation of the Boeing 767 idea in the 21st century.

Project 7E7 can sometimes be seen with the suffix Y2. It is the first implementation of Boeing's large-scale Yellowstone Project program, which involves updating the company's entire line of aircraft. At the same time, the letter E in the index is usually explained with the words Efficient or Environmentally friendly, or simply Eight (the letter was replaced by the number 8). In the summer of 2003, following a large-scale competition, the company chose the name Dreamliner (the leaders were also the following variants: eLiner, Global Cruiser and Stratoclimber).

In 2004, the Japanese airline All Nippon Airways (ANA) became the launch customer, signing a contract for 50 aircraft with deliveries to begin in 2008. Initially, the contract provided for the delivery of 30 787-3 airliners, with a capacity of 290-330 passengers in a single-class configuration (for local transportation), and 20 787-8 - long-haul 210-250 local aircraft in a 2-class configuration (for long-haul flights to Denver, New -Delhi and Moscow). The 787-3 and 787-8 were to be the base models, with the 787-9 to appear a few years later.

The Boeing 787 was the first aircraft whose fuselage base section was a monolithic composite part, rather than a composite of aluminum sheets (with other advantages, this eliminated the approximately 50 thousand rivets used in conventional structures). As power plant The engines chosen were Rolls-Royce Trent 1000 and General Electric GEnx. According to the developers' calculations, the aircraft was supposed to be 20% more efficient than the 767 model. At the same time, the long-haul models 787-8 and 787-9 were supposed to have an ETOPS 330 certificate, allowing them to continue flying for 5.5 hours if one engine fails.

By 2005, the Boeing 787 already had a backlog of orders for 237 aircraft. Moreover, Boeing offered the -8 model for only $120 million, which seemed almost like a price dump. However, in 2007, aircraft began to rise in price and added $30-40 million to the original cost.

Industrial cooperation

In 2003, it was decided that final assembly of the aircraft would be carried out at the Boeing plant in Everett. A feature of the new production is the minimization of production volume at the plant itself. Boeing greatly expanded the capabilities of its contractors, who were now able to produce fairly complex and large prefabricated structural elements. This greatly simplified the production line in Everett, reduced production time, and only about 1,200 people were involved in final assembly (about the same number of people work on the production of SSJ 100 airliners in Komsomolsk-on-Omur). Despite many problems at the initial stage of the project, later this scheme began to justify itself.

The Boeing 787 contractor network is considered one of the most extensive and complex in aviation history:

• Center section and wing consoles - Mitsubishi Heavy Industries (Japan)
• Horizontal tail - Alenia Aermacchi (Italy) and Korea Aerospace Industries (Republic of Korea)
• Fuselage sections - Global Aeronautica (Italy), Kawasaki Heavy Industries (Japan), Spirit Aerosystems (USA), Korean Air (Republic of Korea)
• Passenger doors - Latecoere (France)
• Cargo doors, interior doors - Saab AB (Sweden)
• Software - HCL Enterprise (India)
• Floor Beams - TAL Manufacturing Solutions (India)
• Cable network - Labinal (France)
• Wing tips, wing fairings, landing gear doors, spars - Korean Air (Republic of Korea)
• Chassis - Messier-Bugatti-Dowty (France/UK)
• Power system control complex, air conditioning system - Hamilton Sundstrand (USA).

To increase the speed of delivery of parts from geographically distant suppliers, Boeing modified 4 747-400 aircraft. These aircraft, known as Boeing 747LCF DreamLifters, transport wings, fuselage sections and other aircraft components to the Everett plant for final assembly.

It is especially worth noting the huge role of Japan in the project. In fact, as of 2017, about 35% of all elements and systems of the Boeing 787 are manufactured in Japan, in particular, almost the entire wing of the airliner is made by Mitsubishi Heavy Industries. Japanese specialists participated in the development of the airliner, and Boeing saved a lot on significant tax breaks from Tokyo.

Description: Boeing 787 Dreamliner. History and description of the dream liner

Final assembly of the first prototypes began in Everett in 2007. The company had problems with weight calculations when assembling the first aircraft. The first 6 airliners turned out to be 2.3 tons heavier than expected. This problem was solved by optimizing the design and replacing some of the steel parts with titanium ones (in 2015, Boeing reduced the amount of titanium used to reduce the cost of production).

However, despite all the optimizations, huge demand for the 787 model forced Boeing to increase its production plan. With the Everethay plant reaching its maximum size, the firm had to find another site for the plant. In 2009, Boeing found a suitable site in Charleston, South Carolina.

Flight tests

In July 2007, the first Boeing 787 prototype underwent a rollout ceremony at the Everett plant. At that time, the airliner had contracts for 677 units, which was a record among wide-body commercial airliners. However, at the time of rollout the airliner was not suitable for flights - many systems had not yet been installed or launched.

The airliner had serious problems preparing for flights. Boeing spent a lot of time resolving difficulties with suppliers, coordinating the characteristics of elements and systems, and preparing for the start of flights. Seeing this, as well as being faced with constant delays in deliveries, some customers began to demand compensation.

The difficulties were also caused by the huge number of innovations in the aircraft, which means a much more complex testing and certification program. Boeing and its partners have paid a lot of attention to research into the performance of aircraft composite elements. At first, it was unknown how these elements would behave under critical loads and long-term use, and a number of scientists also feared that in the event of a fire, the new composite elements would begin to emit toxic gases.

In 2007, the new Rolls-Royce Trent 1000 engine was certified. Six months later, the General Electric GEnx-1B engine received certification. Soon, the engines began to be installed on aircraft to test power systems.

In 2009, the first fully assembled prototype underwent a flight simulation test to test all systems. The characteristics were satisfactory, however, the excess of the weight of the airliner over the planned one (by almost 8%) led to a reduction in the flight range to 12,800 km (the planned figure was about 15,000 km). This led to some airlines beginning to refuse deliveries of the first aircraft, waiting for Boeing to solve the problem of overweight in subsequent series.

Finally, in December 2009 (2 years behind schedule), the Boeing 787 Dreamlier made its first test flight from Paine Field in Everett.

The flight test program included 6 aircraft: 4 with Trent 1000 engines and 2 with GEnx-1B64 engines. Flights were deployed to full plan after completion of the readability tests of the wing: it withstood a load 150% higher than the maximum calculated load and did not collapse (the wing was bent 7.6 meters from the rest position).

The aircraft's first international display was the 2010 Farnborough Airshow. At the time, it was stated that the first aircraft would be delivered to Japan's ANA in 2011. At the same time, to speed up testing, 2 more aircraft were included in the group of test aircraft.

In November 2010, one of the prototypes made forced landing in Texas due to smoke in the cabin and a fire hazard. It turned out that the electrical fire in one of the compartments was caused by foreign objects. After electrical modifications and software, flights were resumed.

During testing, problems with new systems were constantly identified. This led to shifts in terms of supplies. By 2011, Boeing had not yet completed certification of the aircraft. By the summer, Boeing and ANA conducted a joint test tour of one of the aircraft - the aircraft made 1,707 flights and visited 14 countries around the world.

The Boeing 787-8, powered by Rolls-Royce engines, received type certificates from the FAA and EASA in August 2011. Certification lasted 18 months—twice as long as originally planned.

Start of operation

At the time of completion of certification, Boeing had production lines ready at its Everett and Charleston plants. It was assumed that they would be able to produce 10 aircraft per month, however, the company had problems with local trade unions regarding working conditions for staff (increasing production volume from 2 to 10 aircraft per month tightened working conditions), which led to a delay in production. The first Boeing 787 left the South Carolina plant in the spring of 2012.

In December 2011, one of the prototypes made a maximum distance test flight from Everett to Dhaka (Bangladesh). The plane flew 19,830 kilometers. This was a range record for 787 size airliners (it broke the A330 record - 16,903 km). The absolute record for commercial airliners remains with the Boeing 777 - 21,602 km.

The first production 787 was delivered to ANA in September 2011. A few weeks later, the aircraft began operating commercial flights from Tokyo to Hong Kong. Tickets for the first flight were sold at auction and the most expensive of them was sold for $34 thousand. Long-distance flights from Tokiw to Frankfurt began operating in 2012.

Based on the results of the first period of operation, ANA stated that the airliner with Trent 1000 engines burns 21% less fuel than the Boeing 767-300ER. Later, based on the results of operation, United Airlines calculated that per one passenger seat, the airliner is 6% more economical than the A330.

Soon, another problem emerged. The new APS5000 auxiliary power unit was more economical than all its analogues, but, as it turned out, it got quite hot during long periods of operation at the airport. In most cases, this was unnoticeable, but, as it turned out, in the case of short-distance flights, the APU did not have time to cool down and overheated when restarted. However, this problem was quickly resolved by design modifications and changes in ground procedures.

The problems didn't end there. In 2012, many malfunctions in the operation of GEnx engines were revealed, due to which aircraft with this power plant did not fly for some time. In 2014, after changing the manufacturing process for composite elements, Mitsubishi Heavy Industries identified manufacturing errors that could lead to microcracks in the wing structures. Ultimately, 42 undelivered aircraft were put through inspection and defect correction procedures. The problem was resolved, but the aircraft were several weeks behind schedule.

However, the overall reliability of airliners continued to grow and, by 2015, reached 98.5% (at the beginning of operation it was about 96%). In 2013, planes spent 5 hours in the air, and by 2014 it was already 12. In 2017, reliability reached 99.3%.

At the same time, airlines, seeing that the airliner is most effective over long distances, began to put it on maximum-range flights that were previously served big planes: Lockheed L1011, Boeing 747 and Airbus A340. Although a smaller aircraft, the Boeing 787 was much more flexible and efficient.

By the summer of 2017, Boeing had delivered 565 aircraft: 340 Model-8s and 225 Models-9. 39 airlines operate these aircraft on 983 routes around the world. The aircraft is also used on the record-breaking flight Perth (Australia) - London (UK) by Qantas airline with a length of 14,499 kilometers.

Market and production costs

The cost of the 787 Dreamliner program is estimated at $32 billion. It is assumed that the program will pay for itself after delivery of approximately 1,100-1,200 aircraft.

The production plan assumes a rate of 14 units per month (168 per year) by 2019. By this time, Boeing will be able to reduce costs by increasing production volumes and optimizing business processes, as well as increase the supply cost of aircraft. It is assumed that the profit margin on the sale of each aircraft will be about 30% (20% for the 737 and 25% for the 777). At the same time, a number of experts believe that Boeing will not be able to significantly improve the economics of two factories located in different parts of the United States, and competition with the A350 and A330neo will not significantly increase the cost of the aircraft.

Design

The Boeing 787 is a wide-body, long-haul airliner equipped with two engines. Being, in general design, a classic modern airliner, it includes many new solutions that have significantly improved its flight and economic performance.

The main innovation is the widespread use of composite materials. About 50% of the aircraft's dry weight is composites, 20% is aluminum alloys, 15% is titanium alloys, 10% is steel and about 5% is other materials.

Aluminum is used primarily in the leading edges of wings, tails and engines. Titanium is used in pylon fastenings and in engines, while some of the power elements are made of steel. Most of the airframe is made of carbon composites and fiberglass.

Distinctive external features of the new airliner include a lowered nose, improved ridged wingtips and engine nacelles with sawtooth chevrons. The design is designed for flights at speeds of about 900 km/h at standard commercial high-rises of 12-13 km.

Flight systems

The main feature of the Boeing 787 onboard complex is a completely new electrical architecture, primarily climate control. Unlike others passenger aircraft, where the air supplied to the cabin is taken from the engines, in the 787 the air is supplied by compressors from environment. This made it possible to significantly remove additional load from the engines and increase their efficiency. The electrical system, with a total power of 1.45 mW, is actively used in stabilizer drives, engine starting systems and brakes. In addition, the anti-icing system has also been replaced - instead of a stream of hot air, the ice is thawed with special heating elements.

The aircraft is equipped with a new automated flight stabilization system in turbulence conditions. This system is new to civil aviation, although it was created quite a long time ago to stabilize the flight of B-2 Spirit bombers.

The Boeing 787 has a full fly-by-wire system. Having been significantly modernized, it is, in fact, a legacy of a similar complex from the Boeing 777.

The aircraft's cockpit is completely new and significantly different from its previous generation counterparts. The interface consists of five large multifunctional LCD displays, as well as two HUD displays as standard (HUD was previously offered as an option). Interestingly, similar cockpits developed by Rockwell Collins for the Boeing 787 in various modifications are also used on the MC-21, Comac C919 and some other new aircraft, and also displays and HUD from this cockpit are installed on the Orion spacecraft created by Lockheed Martin and NASA. The classic solution in the new cockpit remains the steering wheel - Boeing is not switching to a side stick.

The main suppliers of avionics for the new aircraft are Honeywell, Rockwell Collins and Thales.

To ensure a significantly increased information flow, the Ethernet complex of the ARINC 664 standard is used. Moreover, part of this network is used to connect passengers to the Internet in flight. In 2008, the FAA announced its fears that passengers could interfere with the operation of the airliner's systems in flight, however, Boeing ruled out such risks since the passenger network is physically separated from the aircraft's systems protected by special protocols.

Power system

Despite the refusal to connect the cabin climate control to the aircraft's engines, it is worth dispelling the popular belief that the Boeing 787 is powered exclusively by lithium-ion batteries. Increased energy consumption also increased generation requirements. The airliner's power system has 7 generators at once: 2 in the engines, 2 emergency in the APU and 1 in the emergency turbine.

The lithium-ion batteries for the aircraft's electrical system are supplied by the Japanese corporation GS Yuasa. The battery complex is made up of two batteries weighing 28.5 kg. The first battery is the main one, it is used to provide power to the aircraft on the ground if the engines and APU are turned off, and also, in emergency mode, it can provide energy to the aircraft if all seven generators of the aircraft fail (which is practically impossible). The second battery is used to start the engines if the APU is turned off, and also supports the operation of auxiliary systems.

The use of lithium-ion batteries has simplified maintenance and increased the efficiency of the power system. It is worth noting that what is new is the use of lithium-ion batteries, and not the idea of ​​batteries itself. For example, a similar battery system has long been used on the Boeing 777, but it uses nickel-cadmium batteries, which are heavier, larger and have less power. Lithium-ion batteries are more efficient and have previously been used by the company in its space business. However, despite the advantages, lithium-ion batteries also have disadvantages, most notably the risks of overheating and fire, which has been a problem for the Boeing 787 several times.

Composite materials

The Boeing 787 is the first commercial airliner to have a composite fuselage, wing and a large number of airframe elements. Each aircraft uses about 35 tons of carbon polymers. The advantage of this material is higher strength with less weight compared to metal alloys. In addition, higher strength made it possible to optimize the design of the airliner and improve its aerodynamic characteristics.

Most of the technologies for creating composite elements were developed during the development of the transonic airliner Sonic Cruiser, as well as during the development of the RAH-66 Comanche helicopter (the share of composites in it reached 60%).

The problem with such a large-scale use of composites is the insufficient experience of its use in a number of structures. For example, unlike metals, carbon composites exhibit very little damage or material fatigue effects, which is assessed as a risk of problems not being detected in a timely manner. When creating the A350 XWB airliner, Airbus also actively used composites, but did not apply them to a number of important structural elements, acting conservatively but reducing risks. Also, a number of experts express concerns that in the event of damage to the fuselage, its harder elements will be more easily destroyed, and in the event of a fire, the composites will release toxic gases.

However, it is worth emphasizing the perhaps excessive dramatization of the problems. Composite materials, although they have never been used on such a scale, are still not an innovation in aviation and the experience of their use does not confirm many concerns. To ensure preventive risk control, Boeing has somewhat expanded its aircraft after-sales service programs (procedures known as 787 GoldCare).

Engines

The Boeing 787 is equipped with two thrust engines. Optionally, customers can choose the General Electric GEnx-1B or Rolls-Royce Trent 1000 models. Engine thrusts range from 28.5 to 34.7 tf, depending on the aircraft modification.

Among the main innovations are the absence of an air bleed system, an improved noise control system, and the presence of two generators in each engine.

To reduce noise, Boeing applied the developments of a number of research programs previously conducted with NASA. New, more efficient sound-absorbing materials have been introduced into the engine design, as well as, of course, new sawtooth chevrons, which ensure a softer mixing of the jet stream with the surrounding atmosphere. Thanks to this, the noise level from airliners in the airport area rarely exceeds 80-85 dB, which is, on average, 10 dB less than that of the Boeing 767 and Airbus A330 (despite the fact that the 787 is the heaviest in its class and its engines are more powerful ).

But even with so many innovations, engines continue to evolve. In 2016, Rolls-Royce began flight testing of the Trent 1000 TEN engines. This engine is an improved version of the Trent 7000 engine from the A330neo (which is an improved version of the Trent XWB from the A350, which in turn is an improved version of the base Trent 1000 from the Boeing 787, such is the cycle of engines in nature). The 1000 TEN models will have a thrust of up to 35.7 tf.

Interior

The width of the Boeing 787 cabin is 5.5 meters, which is significantly greater than the width of the Boeing 767 cabin (4.72 m) and is already close to Boeing salon 777 (5.84 m). Among competitors, the cabin is superior to the A330 (5.28 m), but inferior to the A350 (5.61 m).

Airliner salons have very wide possibilities for customization, so different airlines salons can be quite different from each other. Seating schemes may vary: 1-2-1, 2-2-2, 2-3-2 in business class, and 3-2-3, 2-4-2, 3-3-3 in economy class. Seat pitch varies from 46 to 61 inches (120-150 cm) in first class, from 36 to 39 inches (91-99 cm) in business class, and from 32 to 34 inches (81-86 cm) in economy class. 32 inches is standard in economy class on most airlines.

The most profitable and popular for airlines is the 3+3+3 scheme in economy class. Similar layouts are used on the Boeing 777 and Airbus A350, but due to the narrower cabin, a similar layout on the Boeing 787 is considered cramped. So, if you are a tall and broad-shouldered person, traveling long distances on a Dreamliner in this configuration is unlikely to be your dream flight.

The windows of the Boeing 787 measure 27 by 47 cm and are considered the largest among civil airliners. This was made possible due to the advantages of a more rigid composite fuselage - it became possible to enlarge the windows without additional structural reinforcement. Another advantage of the new windows is the absence of curtains: instead, electrochromatic glazing is used - particles are introduced into the window glass that can change the degree of light absorption when exposed to electricity. In fact, passengers can change the transparency of the windows at the touch of a button. Although the glass still does not become completely opaque, so they still left a curtain at the porthole in the toilet.

Another innovation in the interior is the complete absence of light bulbs. A network of LED lighting is responsible for lighting. In general, such technology in aviation is not new: such elements have long been installed as an option on the Boeing 777 and some Airbus airliners, but now it is used on a larger scale and has already been introduced into the base. Lighting can change colors, which is useful for increasing comfort levels.

Despite the fact that Boeing abandoned the use of the classic air supply system between engines, the new electric compressor atmospheric system creates a pressure in the cabin corresponding to an altitude of approximately 1800 meters (the cabins of most older aircraft have a pressure corresponding to an altitude of about 2-2.5 kilometers) . Humidity levels in the cabin can be adjusted by the crew depending on the number of passengers, but on average are maintained at 15% (previously humidity levels were around 4%). The aircraft again owes many of these advantages to the composite fuselage, which can withstand greater internal pressure and is not subject to corrosion. Also, of course, the quality of the internal atmosphere is maintained by a rather complex system of internal filters and air conditioners, and the absence of a classic air bleed system from the power plant prevents harmful gases from entering the cabin from the engines.

Modifications

The first and basic version of the airliner is the 787-8 model, which appeared in 2009. Later, in 2013, a stretched version of the 787-9 was created, followed by the largest version, the 787-10, which is currently undergoing testing. In the ICAO certification documents they are listed under the indexes B788, B789 and B78X.

Initially, Boeing intended to create a rather modest in its characteristics, but very economical airliner model 787-3. It was supposed to accommodate 290-330 passengers and fly at a distance of up to 5,650 kilometers. The aircraft was supposed to replace the Boeing 757-300 and Boeing 767-200, and to ensure the ability to work with underdeveloped airfields, it was planned to reduce its wing span by replacing the ridge tips with classic winglets. However, such a short range was not in demand by airlines and the advantages of the aircraft did not change this: by 2010, operators replaced orders for the -3 model with the -8 model and the project was closed in favor of the older aircraft of the family.

Boeing 787-8- basic option. The aircraft can accommodate 242 passengers in a 2-class configuration and 359 in a single-class configuration, with a limit of 381. The flight range in a standard configuration is 13,621 kilometers. The aircraft is the smallest and lightest in the family (if, of course, 227.9 tons can be considered light). The Boeing 787-8 was introduced to the market in 2011 and replaced the Boeing 767 aircraft models 200ER and -300ER. The aircraft is quite popular, approximately a third of all orders are for this version, and at the end of 2017, 346 of them are already flying in airline fleets.

Boeing 787-9- an enlarged version, which now turns out to be average in the family. The fuselage of the airliner was lengthened by 6.1 meters (62.81 versus 56.72 for the -8 model). In addition, the aircraft became heavier by 26 tons (up to 254 tons). The capacity is 290 passengers in a two-class layout and 406 in a single-class layout, with a limit of 420 people. The flight range increased slightly and reached 14,140 kilometers. Interestingly, the increase in range was achieved not by increasing the amount of fuel, but by introducing a new active boundary layer control system and improving the aerodynamics of the airliner. Despite all the similarities between the models -8 and -9, these aircraft have many design differences: the wing, fuselage and many systems have been redesigned and improved.

The Boeing 787-9 is a replacement for the older Boeing 767-400ER and a direct competitor to the European Airbus A330. The plane first took off in 2013, and in 2014 it was transferred to the launch customer - airlines Air New Zealand. At the end of 2017, 254 aircraft of this model were delivered.

Boeing 787-10 was the result of active lobbying by Emirates and Qantas. It was not originally planned, but after its creation it finds itself somewhat outside its niche, entering into competition with older models: the Airbus A350-900 and Boeing 777-200ER.

The fuselage of the aircraft was again lengthened by 5.47 meters (68.28 versus 62.81 for the -9 model). The capacity reached 330 passengers in a 2-class layout with a maximum of 440 people. The amount of fuel in the airliner's tanks remained the same, so the additional mass cost it a range reduced to 11,908 km.

Structurally, the -10 model is 95% unified with the -9 model, and the lengthening of the fuselage was achieved by adding two sections in the front and rear sections. The chassis was also strengthened, and the engines were boosted to a thrust of 34.7 tf.

At the end of 2017, Boeing is conducting certification tests, in which 3 aircraft are participating: 2 with Trent 1000 TEN engines and 1 with an uprated GEnx-1B engine. The aircraft will be assembled in Charleston, South Carolina. Deliveries will begin in early 2018.

Other modifications

By the beginning of the 2020s, Boeing plans to create several additional modifications of aircraft, including cargo and special transports. In 2009, the company offered its newest aircraft as aircraft No. 1 and No. 2 to the US Air Force for transporting senior officials, but the military still prefers to use time-tested machines.

Exploitation

At the end of 2017, Boeing had a portfolio of orders for 1,283 model 787 aircraft, of which, by the summer of 2017, 565 had already been delivered: 340 model -8 and 225 model -9. 39 airlines operate these aircraft on 983 routes around the world. The aircraft is also used on the record-breaking flight Perth (Australia) - London (UK) by Qantas airline with a length of 14,499 kilometers.

The largest operators are ANA (59), Japan Airlines (33), United Airlines (32) and Qatar Airways (30).

Operational problems and incidents

At the end of 2017, the Boeing 787 was not involved in serious accidents or disasters that led to the destruction of the aircraft or loss of life. However, being a completely new airliner that incorporated a large number of new technologies, in the initial periods of operation the aircraft was susceptible to “childhood diseases.”

At the beginning of their operation, aircraft from ANA and United Airlies were sent for Boeing inspections several times due to problems with the fuel system (including accounting) and electrical failures. Later, difficulties arose with sensors, on-board locators and aircraft engines. In 2016, while preparing to take off, an Ethiopian Airlines plane jammed and the front landing gear was damaged: the plane received minor damage, and a flight attendant was injured in the cabin.

The most famous problem of the Boeing 787 was accidents caused by new lithium-ion batteries. In 2013, during a flight on board an ANA airliner, signs of fire appeared. The plane made an emergency landing at Takamatsu Airport and was evacuated. An inspection showed that the fire occurred in one of the battery units. After some time, the same thing happened to a JAL airliner. At that time, these airlines operated 24 aircraft - half of all Dreamliners delivered. Soon, the FAA issued a directive removing the entire Boeing 787 fleet from service until the cause of the accidents was determined.

After investigation and testing, it turned out that the battery life on airplanes is about 52,000 flight hours, and not a million, as Boeing stated. The cause of the accidents was a lack of lithium-ion battery design - while more efficient, they are also less stable and, in case of malfunction, can catch fire, and the safety measures provided were ineffective.

The battery circuits, their support systems, as well as their production at Boeing in the battery manufacturer, the Japanese GS Yuasa, were checked and revised. The idea of ​​replacing lithium-ion batteries with nickel-cadmium batteries was discarded, since such battery packs would be larger and would weigh three times as much.

Companies have taken additional safety measures and upgraded battery packs. By the end of 2013, the FAA conducted additional certification tests of the airliners and made changes to operational documentation. However, in Japan, already in 2014, traces of battery overheating were detected twice more during maintenance, but after the introduction of new equipment and maintenance methods, such incidents stopped.

The Boeing 787 is a wide-body aircraft designed to transport passengers, the Dreamliner or “Dream Airplane,” created by specialists from The Boeing Company. Today this airliner is very popular among air carriers around the world. The reason for this is excellent specifications and nice aircraft design.

Short story

The life of the project begins in 2004. On April 26 of that year, Boeing’s new creation, a project codenamed 7E7, was highlighted in the media as an improved prototype of the Sonic Cruiser. Already in January 2005, the official name 7E7 was announced - on Boeing 787.

A year later, one could see a model of a finished aircraft with a specific design. 4 years later, after a series of lawsuits related to the delay in delivery of aircraft life support parts due to the fault of manufacturers, On December 15, 2009, the Boeing 787 Dreamliner took off.

The aircraft participated in exhibitions, for example, at Farnborough, one of the world's largest air shows. Get acquainted with interesting design The Dreamliner was available to visitors of MAKS 2011.

The first delivery of the Dreamler was made on September 25, 2011. Test piloting was carried out on July 2, 2011 on the route Seattle - Haneda. The aircraft was tested with the participation of All Nippon Airways (ANA). The Boeing 787 was awarded an official certificate confirming the Dreamliner’s ability to carry passengers on August 26, 2011. The aircraft entered mass production and already made its first flight on October 26, 2011.

The Boeing 787 is the world's first aircraft with a monolithic main section fuselage. More than 45 thousand rivets are used in conventional prefabricated aircraft: new model made it possible to save money due to the solidity of the body.

Total development costs for the Dreamliner exceeded $32 billion.

Unrealized project

Interestingly, the history of the Dreamliner dates back to the late 1990s. At this time, leading Boeing engineers and designers came to the conclusion that the Boeing 767 model was hopelessly outdated, and that a new competitive solution was required - the Sonic Cruiser.

Unfortunately, due to the tragic events of the Twin Towers on September 11, 2001, the expensive project was postponed indefinitely. In addition, the Boeing 787-3 – for 295 passengers with a flight range of over 6.5 thousand km – was not put into production. The aircraft was to be used for short-distance transport. Considered as an alternative to the Airbus A300 and Boeing 767 in Japanese domestic airlines. But fate decreed otherwise, and the project was closed on 12.2010 in favor of the 787/8 model.

Design

The design of the long-haul airliner includes lightweight composite materials, modern communication systems, and highly efficient engines. According to the manufacturer, this model is 20% more fuel efficient compared to the previous version. The Dreamliner's fuselage parts are manufactured in Washington.

The body contains:

• 50% - composite materials - body;
• 20% - aluminum - in the wings, engine and tail;
• 15% - titanium alloy - in fastenings;
• 10% - steel - strength elements;
• 5% - other materials.

As of the end of 2017, over 599 aircraft were produced. The cost of one Boeing varies from 225 to 306 million US dollars.

The average piloting speed of this aircraft model is 900 km per hour. Flight altitude varies from 12 to 13 km. – standard indicator for passenger transportation.

Motors are used with low noise levels from:

• General Electric;
• Rolls Royce.

The luggage compartment capacity is 2 times higher than that of the previous model.

Cockpit

The cockpit of the “Dream Liner” involves the use of wide-format screens for flight control: they, like military airliners, have a head-up display (HUD), recording any information.

The cabin is strikingly different from all previous designs by Rockwell Collins:

• 5 liquid crystal displays are connected to the interface;
• 2 HUD displays;
• Ethernet Internet standard – ARINC/664, protected by multi-stage security protocols that exclude access by ordinary users.

The same cockpit is used in the MS-21 and Comac C919, on the Orion space models.

Pilots note that the cockpit is easy to use and intuitive. The energy system is a consolidation of 7 powerful energy generators:

• emergency – 2 pcs.;
• V jet engine- 2 pcs.;
• in the emergency turbine - 1 pc.

Lithium-ion batteries are the most effective solution for aircraft, produced by GS Yuasa - 2 pcs. weighing 29 kg each. The first provides Boeing with an uninterrupted supply of energy while on the ground and is capable of operating in emergency mode in the event of generator failure. The second is used to start engines in the event of an auxiliary power unit shutdown. Used to maintain the functioning of auxiliary aviation systems. Despite the many advantages, the new battery system has a drawback associated with a higher fire hazard compared to the nickel-silicon system.

Cabin

The cabin of the Boeing 787 aircraft is equipped with last word equipment: the extensive dimensions of the interior are 5.5 m, which makes it an ideal option for customization to suit the needs of different categories of passengers: from economy class to super VIP and business clients.

The gap between the seating arrangements is:

• 45-60 inches or 115-145 cm for 1st grade;
• 90-100 cm or 35-40 inches for the “Business” class;
• 85 cm or 33 inches for Economy class.

The most common combination is 3+3+3 for Economy class passengers. For tall and large passengers, this seating arrangement is not comfortable during a long flight.

The size of the porthole, which, by the way, does not have curtains, is 25 x 45 cm - this is the highest figure of all standard liners. The glass is capable of automatically adjusting the absorption of light in the cabin. In addition, buttons have been developed for passengers that allow them to quickly change the transparency by simply pressing. They left the curtain in the toilet.

There are no light bulbs in the cabin of a Boeing 787! Instead, LED lighting is used, the color and brightness of which can be adjusted.

There is a new adjustment system in the cabin atmospheric pressure at the level of 1.8 thousand m. For comparison, in earlier models the pressure was maintained at the level of 2-2.5 thousand m. Now, thanks to innovations, no harmful exhaust gases enter the cabin, and the moisture level in the cabin tends to 15 %. Previously, at Boeing it was at around 4%.

Another distinctive feature of Boeing is the increased size of the toilets, which allows even people in wheelchairs to travel. The overhead bins in the cabin can safely store 4 huge suitcases, and the Smoother Ride Technology flight system allows passengers to feel comfortable even after getting into an accident. air pocket and the turbulence zone.

Sensors in the aircraft cabin allow you to track the slightest changes in air pressure, and the flaperon system is adjusted automatically using the latest computer technology.

Interior layout

The following factors were taken into account when creating:

• spaciousness;
• comfortable light;
• big windows;
• wide shelves for luggage;
• availability of displays for each passenger.

Production

Since 2016, the number of aircraft produced per year has been increased to 168. This is 14 Boeing 787s per month. As of May 2018, 691 units were produced.

Manufacturing facilities are located in Everett, USA. Moreover, for the most part, finished parts are assembled at the factory. 1.2 thousand people are involved in the process.

The company's contractors are based in different areas of the world. Thus, the wings are produced by Japanese Mitsubishi Heavy Industries, the doors by the French Latecoere, the tail by the Italian Alenia Aermacchi and the Korean Industries Aerospace, and the chassis by the joint British-French corporation Messier-Bugatti-Dowty.

Aircraft parts are delivered from the manufacturer to the customer on a specially created Boeing 747 LCF DreamLifter production aircraft, of which Boeing has 4.

Japanese engineers played a key role in the project: 35% of all components of the airliner in 2017 were manufactured in Japan. In addition, it was the Japanese who took an active part in the design and development of the Dreamliner.

Aircraft modifications and their costs

The Boeing 787 today has 3 main modifications:

• Boeing 787-8 worth $224.6 million;
• Boeing 787-9 worth $264.6 million;
• Boeing 787-10 worth $306.1 million.

Among the most popular Boeing 787 operators:

• American Airlines;
• Air: Canada, Europe, India and Austral;
• Aeromexico;
• British Airways;
• China Sothern Airlines;
• United Airlines;
• Norwegian Air Shuttle and many others.

The Boeing 787 Dreamliner is an aircraft of the 21st century that will take passenger transportation to a new level of development. High level The comfort and safety that the developers of the Boeing 787 concept offer to their customers allows this model to be, along with the Airbus, the most popular and economical aircraft of its time.

Successful solutions and the ability to choose 1 of 3 high-quality aircraft of the Boeing 787 series allow us to recognize that this aircraft has enormous design potential. This is why there is a demand for Dreamliner all over the world. Such models are the future of air travel.

The Boeing 787 Dreamliner, or Boeing 7E7 as it is also called, is an aircraft with a wide body and jet capabilities for passenger transportation. It was developed by the US corporation Boeing Commercial Airplanes. The liner is used for medium and long distances.

In contrast to the changes being carried out, the 787th ship can accommodate from 210 to 380 passenger seats on board. The flight range is designed for 15,000 kilometers.
The Dreamliner was developed to replace the Boeing 767 and become competitive with the European wide-body airliner Airbus A330.

A Brief History of the Boeing 787-800

In the 90s the corporation "Boeing" began drawing up plans for a program to replace the 767 aircraft. Initially, in 2001, the idea of ​​producing passenger plane at supersonic speed. This would help reduce the flight hour. The development was approved, and it acquired the name Boeing Sonic Cruiser.

Major American air carriers, including Continental Airlines, have given their consent to the project to produce a high-speed aircraft. Then came the disaster of September 11, 2001. The cost of petroleum products and fuel began to rise, so airlines changed their minds about speed. It was decided to focus on the economical use of the ship's fuel energy. That is why in December 2002, the Boeing Sonic Cruiser project received official status as canceled.

The end of winter 2003 - a new project arises. It began to be designated Boeing 7E7.

That summer, the 7E7 took on the additional name Dreamliner.

On April 26, 2004, Japan's All Nippon Airways was the first to order 50 aircraft for the Dreamliner. The first deliveries were planned for 2008.

On January 28, 2005, the corporation announced that the latest aircraft will begin production under the name Boeing 787 Dreamliner. This became the final name.

The Boeing 787 prototypes include the following improvements:

• Boeing 787-3– used for medium distances with the possibility of significant congestion.
• Boeing 787-8– an aircraft with basic equipment. Most popular.
• Boeing 787-9– an improved elongated sample of the previous model. The aircraft is equipped with large passenger seats.
• Boeing 787-10– is just in the process of production.

Technical characteristics of the airliner

The basic model of the vessel was named Boeing 787-8.

• The ship can accommodate from 234 to 296 passenger seats when flying at a distance of 14,100,000 to 15,200,000 m.
• Length – 5600.70 cm.
• Height – 1600.90 cm.
• Wing span – 6000.1 cm.
• The maximum possible cruising speed is 913,000 m/sec.
• The highest possible speed is 945000 m/sec.
• Interior width – 500.49 cm.

Under each wing, arrow-shaped, in special recesses there are two turbojet engines:

• GEnx-1B from the manufacturer General Electric;
• Rolls-Royce Trent-1000.

The aircraft was made from numerous composite components, which are based on carbon compounds. The following materials were used:

• on lifting surfaces of Boeing 787;
• fuselage;
• tail structure;
• doors.

The use of composites makes it possible to make the liner more durable with a reduced carrying capacity of the entire unit, which, meanwhile, has a positive effect on the efficient use of fuel.

Internal filling of Boeing 787-800

Boeing 787 800 cabin layout has two classes:

• business class with 46 seats
• economy class, which can accommodate 112 passenger seats

The latest technologies were taken into account when developing the aircraft's interior.

1. The creators made sure that the plane was spacious. The ceiling was designed so that its shape resembles an arch. This allows you to feel more spacious than in the aisles of other aircraft models.
2. The lighting system is based on LEDs, which change color depending on what stage of flight the ship is at.
3. The window size is 65% larger compared to other models. Conventional curtains were replaced with an electrochromic dimming system.
4. The luggage compartments in the 787-800 are expanded in size by 30%, which is also larger than in other airliners.
5. Boeing 787 has newest system avionics ARINC 661. To display flight-related messages, each seat is equipped with a wide multi-function display.
6. The cockpit for pilots (designed for 2 people) is similar to the one equipped on military vessels. The windshield has a head-up display (HUD) system. This helps you keep track of important flight status messages.

Soon the creators plan to technologically improve the use of FLIR infrared scanning. This will allow the airliner pilots to “see” through the clouds.

If we talk about how to choose a Boeing 787 800 best places , then here the choice is a whole salon. Regardless of the class, be it business or economy, this aircraft provides the opportunity to fully enjoy the flight without experiencing any discomfort.

Currently, only one improved model, 787-800, is in operation. The ship first took to the air in the winter of 2009. The testing period for commercial use ended in mid-2011. Then, in August, the plane was certified by American and European experts that the airliner was ready to fly.

Boeing 787 Dreamlineris a new generation aircraft that was developed to replace the Boeing 767. Currently, many airlines around the world have already replenished their fleet with the Boeing 787. Unfortunately, Russian airlines do not yet have the opportunity to offer flights on this aircraft to their passengers. However, the list of customers includes such airlines as and. So what is the superiority of the new long-haul airliner you will find out in our article.

Boeing787 (Boeing 787) history

Boeing 787Dreamliner (Boeing 787 Dreamliner)– is a wide-body twin-engine long-haul jet passenger aircraft developed by the American concern Boeing in April 2004, to replace the Boeing 767 aircraft model. Initially a production and development project Boeing 787Dreamliner designated as 7E7. The first display of the Boeing 787 aircraft took place on July 8, 2007 at the plant in Everett, Washington, USA. However, the first test flight took place only on December 15, 2009. Certification Boeing 787 took place on August 26, 2011. Development Boeing 787Dreamliner was carried out jointly with foreign companies, including with the participation of Russian companies.
