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. Visitors to MAKS 2011 could get acquainted with the interesting design of the Dreamliner.

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. Conventional prefabricated aircraft use more than 45 thousand rivets: the 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 At this time, leading Boeing engineers and designers came to the conclusion that the Boeing 767 model was hopelessly outdated, and that a new competitive solution was required - the Sonic Cruiser.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 level noise 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.;
• in a 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 the latest technology: the extensive dimensions of the interior are 5.5 m, which makes it an ideal option for customization to suit needs different categories 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.

The cabin has a new system for regulating atmospheric pressure at a level of 1.8 thousand m. For comparison, in earlier models the pressure was maintained at a level of 2-2.5 thousand m. Now, thanks to innovations, harmful exhaust gases do not enter the cabin, and the moisture level in the cabin tends to 15%. Previously, at Boeing it was at around 4%.

One more distinctive feature Boeing's toilets are oversized, allowing access even for people in wheelchairs. The upper shelves in the cabin can safely store 4 huge suitcases, and the Smoother Ride Technology flight system allows passengers to feel comfortable even after entering a pocket of air and turbulence.

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.

The Boeing 787 Dreamliner is an aircraft of the 21st century that will take passenger transportation to a new level of development. The high level of 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.

This airliner radically changed passenger air transportation, and now we will tell you how it did it. Boeing 787 Dreamliner aircraft.

At first glance, there is nothing remarkable about the Boeing 787 airliner. The new mid-size airliner, with a standard design and power output and a modest maximum range, is basically little different from the others. It’s just that in the context of the global crisis, another passenger airliner was introduced to the market.

It would seem that the technology in which billions have been invested has not changed anything. However, if you think so, then you are most likely mistaken...

This is due to the fact that the more revolutionary the new technologies and ideas, the more problematic the details. More than likely, the Boeing 787 currently represents our future, both literally (its operational life lasts until 2028) and figuratively. It is the most sophisticated airliner currently in use in today's economic climate, and is unlikely to be seen again.
something better.

It is more environmentally friendly, cheaper and more comfortable than others, which is why 58 airlines around the world have already ordered 982 aircraft worth more than $169 billion.

How does the Boeing 787 make the dream of cheaper air travel a reality?

Fuel consumption and emissions are reduced by 20%. But achieving this was not easy.

An important aspect of ultra-high performance is the combination of advanced technologies and new materials. Half of the main parts of the aircraft, the body and wings, are made of composite materials (reinforced carbon fiber plastic). They are lighter, stronger and much more versatile than traditional pure metals.

If you compare it with the Boeing 777, which was made of 12% alloys and more than 50% aluminum, you can easily understand how this aircraft contributed to the development of the airline industry.

New materials and control over the assembly process make it possible to consume 80% less aluminum and fastening parts than in the Boeing 777. The Boeing 787 has fewer than 10,000 holes in the fuselage, while the Boeing 747 has more than 1 million. This saves cost and production time while improving aerodynamics. They also removed 96 km of copper wires, not only reducing the weight of the machine, but also optimizing the electrical network.

The Dreamliner is equipped with a state-of-the-art electronic system that, despite all bleed air and hydraulic force with electric compressors andpumps, spends 35% less engine power.

5 facts about the Boeing 787 Dreamliner

1. Implementation

The aircraft was first shown on July 8, 2007 in Washington. By this time, orders for 677 vehicles had already been received.

2.Older brother

The Boeing 787 has an older brother, the extended version of the Boeing 787-9, which came out at the end of 2014.

3. Even more

In 2014, the production of the Boeing 787-10 aircraft for 330 passengers was announced, and more than 100 orders have already been received for it.

4. Assembly

Until 2011, the aircraft was assembled at a plant in Everett, but then assembly began in New
Charleston.

5. First

The first Dreamliner was received by the largest Japanese airline, All Nippon Airwoys, in September 2011.

Did you know?

The Boeing 787 consumes 20% less fuel than the same size Boeing 767.

Compatibility

The Boeing 787 Dreamliner is designed in accordance with the structure of airports and their runways. The steering angle is 650 within a radius of 42 meters.

The new wing anti-icing system uses electro-thermal heating mats on the flaps and improves aerodynamic performance.

Also, this aircraft has significantly improved performance characteristics of the wing's lifting force thanks to the variable wing and bending of the tips, which increases lifting force.

This efficiency greatly helps the work of the “heart” of the Dreamliner airliner: its turbojet engines. The Boeing 787 uses both Geperal Electric GEnx and Rolls-Royce Trent 1000 engines - each of themprovides a maximum thrust of 280 kN and a cruising speed of Mach 0.85 (918 km/h). (thanks to commenters for the correction).

The housings and blades of the engine turbines, as well as the nozzles, are made of lightweight composite materials, which allows them to enter the operating thrust mode at a lower temperature, and this seriously reduces hydrocarbon emissions into the atmosphere and makes the aircraft much more environmentally friendly.

And finally, the soundproofing of the aircraft cabin is ensured by a specially designed new form engine nacelles. They are so advanced that they are ahead of the engines of others passenger aircraft for two generations.

The trailing edge of these nacelles has a serrated shape, which reduces engine noise due to a smoother mixing of the jet stream with the surrounding air and, in turn, seriously saves on noise-absorbing materials and
reduce the weight of the aircraft.

Therefore, despite the first impression, the new Boeing is a real wolf in sheep's clothing, which has numerous improvements, including only energy-saving lighting. All this makes it an extremely promising aircraft.

And you know what's most interesting?

Based on Boeing sales, there's a good chance you'll be flying one of these in the near future.

The Boeing 787-9 passenger airliner is a successful modification of the original version of the Boeing 787 Dreamliner, and this is observed in absolutely all parameters of this aircraft.

The main feature of the Boeing 787-9 passenger aircraft is that, compared to other models of this family, it consumes 20% less fuel, and at the same time remains a more environmentally friendly mode of transport due to reduced emissions of harmful substances into the atmosphere. Also, the cabin of the aircraft is 40 cm wider than that of the predecessor Boeing 767, which made the seats more comfortable and the aisles clearer. The size of the toilets and luggage racks have increased.

The windows on the Boeing 787-9 are 46 cm high, which is 30% larger than most aircraft of this size, and are equipped with adjustable electrochromic dimming - their brightness is adjusted with buttons. The serrated edges of the engine nacelles reduce noise levels by 60% both inside and outside the cabin. There are monitors on the backs of the seats and entertainment programs are provided to them. Passengers can use the Internet.

Aircraft developers designed the Boeing 787-9 aircraft to immediately replace 5 obsolete passenger airliners: Boeing 767-400ER, McDonnell Douglas MD-11, Lockheed L-1011, A330-300 and A340-200, and Lockheed L-1011.

The Boeing 787-9 made its first flight on September 17, 2013, was certified in mid-2014, and began commercial operation on August 7 of the same year. Currently, production of the aircraft continues. Today, 683 aircraft of this modification are used by more than 20 airlines - Air China, Air France-KLM, American Airlines, British Airways, Hainan Airlines, Japan Airlines, LATAM Airlines Group, Qatar Airways, Vietnam Airlines, Virgin Atlantic Airways, Xiamen Airlines, etc.

Location and numbering of seats in the cabin, seating diagram on the Boeing 787-9 aircraft. The best and least comfortable seats on the plane

Hainan Airlines has 13 Boeing 787-9 aircraft in its fleet.

Business Class:

Business class is traditionally located in the nose of the aircraft and occupies five rows in a 2-2-2 layout. Row numbering starts from row 11. All business class seats are quite comfortable. 11 row equipped with bassinets for babies.

The seat pitch in business class ranges from 185 to 203 cm. The seats fully recline into a bed for a more comfortable stay.

There is a 16-inch touchscreen entertainment system on board, equipped with a BOSE noise-cancelling head for a personalized viewing experience. During the flight, you can connect to the Internet via onboard Wi-Fi, making it easier to communicate with friends and family. Each seat has a charging port compatible with any plug, allowing you to charge your electronic devices at any time.

Economy class:

The seat configuration in economy class is 3-3-3 with a pitch between them from 78 to 81 cm. Unlike business class, economy class has a 9-inch touch screen equipped with an entertainment system with many new shows and music.

• 31 row located behind the utility room area. It is equipped with baby bassinets. For parents and babies, of course it is comfortable places, but if you want to avoid unnecessary noise coming from children, then give preference to other rows.
• 45 row located in front of the service area, so it can also be quite noisy.
• 46 row with increased space at the front, which benefits passengers who like to stretch their legs. Since there is an emergency exit in front, nothing can be placed on the floor.
• 58,59,60 rows with a reduced number of seats in a row due to the narrowing of the fuselage. The places are convenient because there are fewer neighbors and you can get up quietly without disturbing anyone. Row 60 is located very close to the toilet and dressing area. For some this fact is a plus, for others it is a minus, but the cost of a ticket to the last row is always lower.

WORLD BISINESS (World Business Class):

World Business Class occupies the first eight rows at the front of the aircraft. The seats are installed in a herringbone pattern, quite comfortable with a pitch of 107 cm. The seats in the first row are located behind the kitchen area and toilets, so additional noise and smell can be heard, and the lights are always on there at night.

ECONOMY COMFORT (Economy class with increased comfort):

Economy class with increased comfort is located from rows 10 to 15. There is nothing bad to say about them; the seats are quite comfortable with a distance between the seats - 89 cm. One can note the less comfortable seats in the 10th row due to the galley located in front - additional noise is possible, and the light may also disturb you at night.

ECONOMY (Economy class):

Economy class is divided into two cabins: the first from rows 16 to 25, the second from rows 30 to 44. Between them there is an emergency exit and four toilets. Average distance between seats

• Row 30 is a comfortable seat, but has some drawbacks. Ahead of the 30th row there is a toilet, therefore, throughout the entire flight, it is accompanied by the frequent movement of passengers, the sound of slamming doors and the flush tank. But there is plenty of legroom.
• Seats 25 rows and 43 ABC - with inconveniences in terms of the toilet located nearby. The backrests of the 25th row seats have limitations in reclining.
• Seats DEG and HJK in row 43 are also not comfortable due to the kitchen area, and seats in row AK in 41 are also not comfortable due to the lack of portholes.

Flight performance

• Maximum speed: 950 km/h
• Cruising speed: 910 km/h
• Flight range: 15370 km
• Aircraft capacity: economy class - 290 passengers, economy/business - 250 passengers, economy/business/first class - 280 passengers

• Unlike other passenger aircraft, where the air supplied to the cabin is taken from the engines (so-called bleed air) with a temperature of more than 600 degrees, passes through coolers and enters the cabin, in the Boeing 787 Dreamliner the air is supplied to the cabin by electric compressors directly from external environment. This eliminates the problem of insufficient air humidity. More humid air inside the Dreamliner provides greater passenger comfort.
• The 787 manufacturing plant is approximately 380,000 square feet in size.

Dreamliner is a dream plane, this beautiful name rightfully belongs to one of the most modern airliners of our time - the Boeing 787.

The aircraft was created in the early 2000s by the American manufacturer of the same name - The Boeing Company, a world leader in the production of aviation and space technology. This is the first airliner model with a superior proportion of composite materials in the design and the introduction of the latest NASA developments. Thanks to this, the 7E7 project has become practical and in demand among air carriers.

History of creation

At the end of the 1990s, Boeing was actively promoting its latest development under the symbol 777. The model was superior to the Boeing 767 in terms of comfort and technological innovations.

These aircraft were rapidly becoming obsolete and needed urgent modernization or a more radical solution, disposal. For Boeing, this issue has become a priority. Soon the management made a verdict: send the 747 model for modernization, and write off the 767 model.

The latter had to give way to a futuristic airliner - the Sonic Cruiser, which was planned as a transonic aircraft that would have no competition in the world. It was intended to provide the new ship with similar passenger capacity characteristics to the 767 liner.

At the same time, it was planned to increase the speed parameters of the aircraft to 1100 km/h.

The technical specifications did not involve breaking the sound barrier, but the project for the aircraft of the future was very promising. It was especially expected on airlines with long flight durations of 10-12 hours. But the project was not accepted for development.

The beginning of the 21st century is remembered by humanity for the largest terrorist attack in America, called 9/11. The tragedy caused a large-scale military operation USA in Afghanistan. The consequence of these events was an increase in the cost of oil. Due to this, development of the Sonic Cruiser was officially discontinued by 2002.

Since the planned fuel consumption of the aircraft of this project could hardly be called economical, and, therefore, operating costs could outweigh the profits from the flights.
However, the developments on the transonic airliner did not go unnoticed.

A month after the inglorious end of the ambitious SC program, Boeing announced the start of a new project - the 7E7. According to the engineers, an airliner with a classic layout was to be born, but using latest technologies from the national project Sonic Cruiser.

The main idea of ​​the engineers contained the following conditions: an aircraft for operation on long-distance airlines with the ability to land at small hub airports.

The new project actually continued the idea of ​​the Boeing 767 airliner in the 21st century.

Among those interested in the fate of the project, the question arose, what does the letter E mean in the 7E7 index? They found different explanations for it, such as Environmentalism (environment), Efficient (effective) and Eight, (No. 8). In addition to this mystery, Boeing announced a competition for the name of the new aircraft. According to the voting results, the slogan “Dreamliner” (dream plane) won.

In 2004, the first customer for the “dream plane” appeared. This is the Japanese airline ANA (All Nippon Airways). The pre-order was amazing in its scale. According to the contract, Boeing committed to build 50 aircraft for the Land of the Rising Sun with delivery of the first aircraft in 2008.

The Boeing-787-9 project was planned on the basis of two airliners, which was supposed to go into production in a couple of years.

A year later, after concluding a contract with the Japanese airline ANA, Boeing accepted orders for the production of 237 Dreamliner units. The most affordable model was the Boeing 787-8, its cost was $120,000,000, which was a relatively low price. However, the low cost did not last long and the plane eventually rose in price by $30 -$40 million.

Among the mass of proposed power plants, preference was given to two aircraft engines:

• British Rolls-Royce Trent 1000;
• American General Electric GEnx.

These power plants allowed the 787-8 and 787-9 airliners to pass ETOPS 330 certification, which regulated the following: in the event of an emergency stop of one engine, the aircraft must continue to fly for 5.5 hours.

It is worth noting the fact that the Boeing 787 Dreamliner is an international development.

This circumstance may reassure those Russians who are dissatisfied with the large volume of foreign technologies in the domestic Sukhoi company.

Boeing's contractors on the 787 project are surprising in their geographic location and overall numbers. Structural elements for the dream aircraft are being supplied from different parts of the globe. The aircraft is assembled in Everett, Washington.

The number of workers involved in the assembly production is 1,200 people. Initially, the scheme for supplying units and parts from contractor countries to the USA was not worked out, but over time, the process got into the right direction and began to pay for itself. The Boeing 787 supplier network is multidisciplinary and central in the history of aircraft manufacturing.

The contractors include the following foreign manufacturing companies:

• center section and wing - Japanese Mitsubishi;
• horizontal tail surface - Alenia Aermacchi (Italy) and South Korean Korea Aerospace Industries;
• fuselage modules - fully international, Italian Aeronautics, Japanese Kawasaki HI, American Spirit Aerosystems and South Korean Korean Air;
• luggage and interior doors - Swedish Saab;
• electronic equipment - HCL Enterprise (India);
• load-bearing floor frame - TAL Manufacturing Solutions (India);
• power line - Labinal (France);
• aerodynamics of wing mechanization, wing tips, landing gear doors, load-bearing spars - Korean Air;
• chassis mechanism - Messier-Bugatti-Dowty;
• power system control, air conditioning complex - Hamilton Sundstrand (USA);
• passenger doors - Latecoere (France).

Japan deserves special mention. According to 2017 statistics, enterprises in the Land of the Rising Sun produced 35% of the elements of the Boeing 787 airliner. Four Boeing 747LCF DreamLifter aircraft were used to deliver large parts to the United States. This is a modernized version of the Boeing 747-400 airliner.

Strong demand for the 787 forced Boeing to open an additional assembly platform in 2009.

It is located in Charleston, South Carolina.

The associated difficulties in innovative solutions and delays in the supply of components increased the estimated project timeline by two years. This made everyone at Boeing nervous. Among themselves, they began to call the liner by an unspoken nickname - Dreadliner (horror plane).

In December 2009, air traffic controllers gave permission for the Boeing 787 Dreamlier to take off. This was the first test flight. The long-awaited event took place at the Paine Field experimental airfield owned by the aircraft plant in the city of Everett.

Design

Boeing-787 is a wide-body passenger aircraft for long-distance flights.

Modern technologies in the manufacture of the airliner have improved its flight performance and at the same time reduced the cost of production.

If we consider the number of materials in percentage terms, then 50% are carbon-based composites, then 15% are aluminum alloys, 10% are titanium and steel alloys, and the remaining 5% are other types of materials.

Passenger cabin plan

The cabin width of the Boeing 787 is 5.5 meters. This exceeds the transverse size of the B-767 cabin (4.70 m) and is slightly inferior to the B-777 (5.80 m). Airliner interior model range 787 may differ from each other. Customization is related to the preference of the customer's company. The arrangement of passenger rows has the following layouts: for business class: 1+2+1, 2+2+2, 2+3+2, and in economy class 3+2+3, 2+4+2, 3+3 +3.

The distance between rows along the aircraft axis: 120-150 cm for first class, 100 cm for business class, and 80-85 cm for third class. Each chair has a built-in personal video monitor.

The most cost-effective seat setup for an airline is the 3+3+3 layout for third class. The presented passenger seating scheme is widely used by its main competitor.

However, for such an arrangement of seats on the plane, the B-787 does not have quite enough fuselage width and, therefore, the aircraft cabin is cramped and uncomfortable for people of impressive build. Tall, broad-shouldered men especially suffer from lack of space during long flights.

One of the innovative solutions on the Boeing 787 is to increase the size of the windows.

With windows measuring 27cm x 47cm, it outperformed all other civilian models. It is worth adding to this that now the windows are not equipped with curtains.

The light transmittance of glass is changed by light-absorbing particles added to the glass. It is called electrochromic or smart glass. The passenger can adjust the transparency by pressing a button, but the window cannot be completely darkened.

There are no light bulbs in the interior lighting. The role of the light source is performed by lines of LED illuminators. Although this lighting function is not considered an innovation, since it has already been used in the Boeing 777 and Airbus models. However, her distinctive feature is complete failure from the lamps in the 787 model, and not partial, as in the aircraft mentioned above.

The advantages of LED illuminators are that they have low energy consumption and change the tone and color of the lighting. The latter feature adds comfort to the interior of a dream airplane.

Business Class

Business class passengers become the owners of the best seats on the Boeing 787. The chairs are large and comfortable in the form of half-booths. They can be folded out into reclining positions if necessary. The seats are arranged diagonally in a herringbone pattern, this provides the passenger with the greatest privacy.

Each seat is equipped with a large video monitor and multimedia system for those wishing to be entertained during the flight.

The passenger is given a set of socks that replace slippers. And if the flight is at night, then pajamas will be offered in addition to socks.

The armrests are raised electrically. There is a small shoe box and a glove compartment for small personal items. At the level of the shoulder joint there is an individual shelf. The front table can be folded in half by pulling it towards you.

The seat belt is equipped with a damper, for those who prefer to sleep fastened. Customer service is personalized, just like in a restaurant. The flight attendant takes the order and brings it on a tray, no trolleys.

There are two toilet rooms. They are 1.5 times more spacious than in economy class. Hygiene products include deodorants and dental care products. It is worth noting that row No. 6 is not popular, as it is located near the toilets.

Engines

The Boeing 787 can be equipped, at the customer's request, with one of two types of power plants: Rolls-Royce Trent 1000 or General Electric GEnx-1B. Each aircraft engine is equipped with two generators.

Developments were used in the design of power plants research projects together with the federal agency NASA.

Among a large number of innovations, the most effective were: the use of sound-absorbing material and sawtooth chevrons on the nozzles of power plants. The latter help the jet stream to dissolve more gently in the atmosphere.

Despite the fact that the B-787 model is more powerful and heavier than its analogues, the noise level is 10 dB less than its predecessor Boeing-767 and the competing aircraft Airbus-A330.

Flight performance compared to competitors

Airbus and Boeing have remained the only major airliner manufacturers since the late 1990s. Having eliminated their main competitors through acquisition, the world's two aviation supercompanies are testing each other's strengths and trying to stay ahead of the curve in using the latest technology.

Over the past 13 years (2005-2017), Airbus has concluded more than 11,830 orders and delivered over 6,500 aircraft to customers. While Boeing accepted more than 11,025 orders and delivered about 6,410 airliners to customers. As you can see, the competition between competitors is very intense. But in the overall standings, Boeing has overtaken Airbus for the sixth year in a row.

Let us consider in the table the flight performance characteristics of modern models that are direct competitors.

Conclusion

At the beginning of 2018, Boeing had a completed order portfolio of 1,283 aircraft of the 787 model series. Of the total number of obligations, more than 600 aircraft were delivered to customers. Among them are 340 Boeing-787-8 units and 260 Boeing-787-9 aircraft.

The aircraft is in active service with 39 international airlines on 983 airlines around the globe.

The dream plane is used on the longest route “Peter (Australia) – London (UK)”. The flight belongs to the airline Qantas, which is the only company that operates the 14,500-kilometer route.

The largest owners of the Boeing-787 Dreamliner are: Japanese companies ANA - 80 units and Japan Airlines - 39 units, as well as the United States United Airlines - 33 aircraft and the Middle Eastern Qatar Airways - 32 airliners.

All of the listed airlines have made large pre-orders for the Boeing 787-10.

It is worth noting the fact that the Russian company Aeroflot did not purchase the B-787 model for its fleet, and judging by the number of aircraft ordered, it gave preference to the domestic development of the Sukhoi Superjet 100 and the French manufacturer Airbus with a preference for the A350-900 model.

is a new generation long-range wide-body aircraft, built to replace the 767 model. It is noteworthy that for the first time in the history of aircraft construction, 50% of the aircraft’s structure consists of lightweight composite materials.

Story

In the late 1990s, sales of long-haul jetliners began to decline, and Boeing began considering a replacement program for these aircraft. The project, accordingly, involved the development of two new models: the 747X - an extended and more fuel-efficient version of the 747-400, as well as the futuristic Sonic Cruiser concept, which could reach a speed of up to 0.98 Mach, while consuming no more fuel than 767 (per due to shortened flight time). As a result, both projects were received coolly by the airlines.

September 11, 2001, the unfortunate terrorist events in the United States, marked the beginning of the aviation crisis and rising oil prices. Demand for air travel had dropped significantly, and airlines needed new, fuel-efficient aircraft. The Sonic Cruiser project did not fit into the new realities, and on February 20, 2002, Boeing officially announced its cancellation.

In January 2003, Boeing unveiled the 7E7 twin-engine aircraft, based on Sonic Cruiser technologies. The company also announced that this aircraft will be the first in the new Yellowstone family.

Yellowstone

Yellowstone is a Boeing project to replace the entire range of civil aircraft with high-tech models. New technologies include the use of composite materials in airframe construction, increased use of electrical systems instead of hydraulic ones, and more fuel-efficient turbojet engines.

The Yellowstone program is divided into three types:

• Boeing Y1 is a project to replace aircraft with a capacity of 100 to 200 passengers. Designed to replace the 737 model
• Boeing Y2 is a project to replace long-haul 767 aircraft. To date, it has been completed and implemented under the name Boeing 787
• Boeing Y3 - a project to replace ultra-long-range aircraft 777 and 747 with a passenger capacity of 300 to 600 people

Dreamliner

In July 2003, Boeing held a competition for best name for 787. About 500,000 people chose the Dreamliner.

On April 26, 2004, All Nippon Airways became the Dreamliner's launch customer, ordering 50 aircraft for delivery in late 2008.

The Boeing 787 is an innovative product because for the first time in history, the aircraft's structure was created from lightweight composite materials rather than aluminum. This solution allows us to significantly reduce the weight of the aircraft, and therefore make it economically profitable. The company promised that the new airliner will consume 20% less fuel than the Boeing 767. Also, in comparison, the 787 will be 40% more efficient, thanks to modern engines and advanced aerodynamic solutions coupled with modern systems.

Cockpit

The aircraft is controlled using a fly-by-wire system. Overall, the cabin architecture is similar to the Boeing 777.

The Boeing 787 cockpit is equipped with multifunction displays. The control system includes the so-called “electronic flight plan” - two screens (one for each pilot), which display taxiing, approach and terrain maps.

Also, by default, the cabin is equipped with transparent indicators in front of the windshield (Huds), which allow you to simultaneously see instrument data and what is happening “outside the window.”

Using a broadband radio communication channel in real time, the automatic diagnostic system sends data to the ground repair service. This system can independently predict the occurrence of certain problems in aircraft mechanisms, which promises to reduce the likelihood of delays and reduce the time spent on diagnosis and repair.

Passenger cabin

The passenger cabin of the Boeing 787-8 can accommodate 296 passengers (in a one-class configuration), 240 passengers (in a two-class configuration), 234 passengers (in a three-class configuration.

The cabin width is 5.5 meters, and is 38 centimeters wider than that of the Airbus A330 and A340. The Boeing 787 has larger windows than any other passenger aircraft (27 x 47 cm). Instead of the usual plastic curtains, the windows are equipped with electrochromic dimming in smart glass.

One of the amazing features of the Boeing 787 is the cabin lighting. Anyone who's ever flown across multiple time zones knows what it's like to sleep mid-flight and be awakened by the flick of a switch and a fluorescent white light filling the cabin. LEDs in the dreamliner's cabin allow the crew to adjust the lighting intensity to suit different phases of flight.

The size of toilets has increased. Now, by deploying the partition between them, you can organize access for people in wheelchairs. The overhead bins have become significantly more spacious, and each of them can accommodate four suitcases with wheels, which is significantly more than the Boeing 767.

The more elastic composite body of the Dreamliner allows the pressure in the cabin to be maintained at a level corresponding to an altitude of 1800 m, whereas in the cabin of a conventional aluminum passenger aircraft the pressure corresponds to an altitude of 2400 m.

The Boeing 787 is equipped with an innovative smooth flight system (Smoother Ride Technology), which ensures passenger comfort during turbulence. Boeing says this smooth flight technology will reduce the number of passengers sick by eight times. Throughout the entire area of ​​the aircraft there are special sensors that detect changes in air pressure, and this is one of the signs of turbulence. Based on sensor readings, the computer system adjusts the position of the flaperons to suppress the aircraft's vertical oscillation.

The cabin pressurization system is organized in a new way. Unlike other passenger aircraft, where air supplied to the cabin is taken from engines with a temperature of more than 600 degrees, passes through coolers and enters the cabin, in the Dreamliner the air is supplied to the cabin by electric compressors directly from the external environment. This eliminates the problem of insufficient air humidity. More humid air in the Dreamliner cabin provides the greatest comfort for passengers.

Modifications

Boeing 787-8 – basic modification. Length 57 meters, wingspan 60 meters, maximum flight range up to 15,200 km. The aircraft is designed to replace the 767-200ER and 767-300ER.

Boeing 787-9 is a modification with an extended fuselage and a capacity of 250 to 290 passengers in a three-class cabin configuration. Flight range from 14,800 to 15,750 km. Boeing expects to replace the 767-400ER with this model. Deliveries to airlines are due to begin in 2014.
