Wide-body long-haul aircraft "Boeing 787" refers to a new generation of technology. It was built to replace the already outdated model 767.
The main difference between the Boeing 787 and its predecessor is its design. For the first time in the history of aircraft construction, fifty percent of lightweight composite materials are used in this model.
Start a new model creation program.the aircraft caused a drop in sales of such long-range airliners as 747-400 and 767. This happened in the nineties of the last century. Boeing has taken on two new models. One of them was a more fuel efficient version of the 747-400. This is a 747X model. The second version of the project involved the development of an aircraft that would consume no more fuel than the Boeing 767, but was able to reach speeds of up to 0.98 M. However, the airlines met these cool models.
In early 2003Boeing presented a draft of the new twin-engined 7E7 aircraft. The model was developed using Sonic Cruiser technology. The company announced that this airliner belongs to the new Yellowstone family.
Yellowstone is a project of Boeing,involving the replacement of the existing model range of civil aircraft with a series of high-tech type. In the design of the liner used lightweight composite materials. Instead of hydraulic applied electrical systems. On these models turbojet economical engines are installed.
The Yellowstone program consists of three sections.The first one is Y1. It involves the replacement of aircraft with a capacity of 100-200 passengers. Project Y2 is designed to introduce new models of long-haul liners. To date, this program is fully completed. Her brainchild was the plane "Boeing-787".
The company is also working on the Y3 project. Models are being developed to replace the ultra-long aircraft 747 and 777, which have a passenger capacity of 300-600 people.
Boeing in 2003a competition was held for the best name for 787 models. Almost half a million people have chosen the Dreamliner option. Already in April 2004, a launch customer was found at Boeing 787. They became the shipping company All Nippon Airways. She immediately ordered fifty aircraft that were to be delivered by the end of 2008.
"Boeing 787" (see photo below) isinnovative product in the field of aircraft. For the first time in its construction, aluminum was replaced with light composite materials. This solution has significantly reduced the weight of the liner, and therefore make it economically advantageous.
Boeing has developed the Boeing 787,whose technical characteristics allow the liner to consume twenty percent less fuel than the 767, and to be forty percent more efficient. This became possible after the installation of modern engines and the adoption of modern aerodynamic solutions in combination with advanced schemes. And at the end of 2004, 237 airliners of the 787th model were ordered from Boeing. In 2012, it agreed to deliver four Transaero Boeing-787 aircraft.
В декабре 2003 г.The Boeing management decided that the Boeing 787 would be assembled in the state of Washington, in the city of Everett, at a factory that was built in the late sixties of the last century to produce the 747th model.
Aircraft "Boeing 787" were created with the participation ofJapan. Companies from this country have done work on the creation of almost thirty-five liner units. The Japanese government supported this project in an amount equal to two million dollars. The assembly of the first Boeing 787 was launched in May 2007.
For the first time, the Boeing 787 rose into the air on 15.12.2009 The flight lasted about three hours. After that, the company developed a nine-month test schedule. In the flight test took part six aircraft. Four of them were engines Rolls Royce Trent 1000, and two - GE GEnx-1B64. In March 2007, he successfully passed the wing load test, which was increased by one hundred and fifty percent compared to the standard one by three seconds. Subsequently, the liner underwent temperature tests and was slightly modified due to the identified shortcomings. Certification of the Boeing 787 was made on August 13, 2011 by the US Federal Aviation Administration. 10.26.2011 the liner made the first commercial flight.
Fifty percent of all the elements of whichmanufactured fuselage "Boeing 787", composed of materials containing carbon fiber. That is why this aircraft is much lighter and stronger than those liners in the production of which aluminum was used. Fifty percent composite materials consist of carbon fiber, twenty percent are made of aluminum, fifteen are made of titanium, ten are made of steel, and five percent are composed of other components.
При сборке "Боинга-787" используют GE Electric and Low Noise General Electric GEnx-1B and Rolls Royce Trent 1000 engines. In the first of them, the turbine blades and body are made only of composite materials. That is why the engine is able at lower temperature conditions to create a working draft. As a result, there is a reduction in hydrocarbon emissions into the atmosphere.
The Boeing 787 has developed more than others.models, the length of the wing. In addition, anti-icing equipment, flap mechanism and other systems are mounted as a single unit. This helps to facilitate their maintenance and reduce the likelihood of damage.
The company has developed three modifications."Boeing 787". These are 3, 8, 9 and 10 models. Each of them has some differences in specific technical parameters. Equal at all, only the diameter of the fuselage (5.77 m), height (16.9 m), maximum altitude (13100 m) and the highest speed (950 km / h).
For the convenience of controlling the aircraft is equippedmultifunctional displays. They are in the cockpit. Management is carried out with the help of an electro-remote system. It includes two screens that display the exit, taxiing, and a map of the area. Transparent indicators are installed in front of the cab windshield. They allow you to control the data devices, without closing the visibility.
The capacity of the Boeing 787 depends on its configuration. From 234 to 296 passengers can board the aircraft.
Designed in the Boeing 787, the cabin is veryconvenient for passengers. The usual plastic blinds here are replaced with electrochromic blackout in the smart glass of the porthole. Amazing features different interior lighting. Its intensity is adjusted by the crew depending on the phase of the flight.
In the 787th model, the size of the toilets is increased.Now they can use people in wheelchairs. More spaciousness in the cabin have upper luggage racks. On each of them can be put four suitcases. The pressure in the cabin is maintained at a level corresponding to a height of one thousand eight hundred meters. In an ordinary aluminum aircraft, it corresponds to 2400 m. Such comfortable conditions are created thanks to the elastic composite liner body.
Comfortable conditions for passengers in the zoneturbulence is preserved by a smooth flight system that is able to suppress vertical oscillations of the aircraft. In a new way in the Boeing 787 organized supercharging system. Its installation allowed the air to be supplied to the salon directly from the environment, and not from the engines, as was the case in previous models.
