The transatlantic liner Boeing 777
In all advertising brochures and descriptionsit is noted that the Boeing 777 is fully developed using computer programs. Journalists and fans of information technologies emphasize the fact that no graphic document has been created in the design and manufacture of the aircraft. All details and assembly sketches were compiled using programming and using computer graphics. Even the assembly of the aircraft was carried out in the virtual space. All work on the design and production of the prototype lasted nearly ten years.
In size, the Boeing 777 is consideredthe largest among civil aircraft. Its length is almost seventy-four meters, and the diameter of the fuselage is more than six meters. The mass on takeoff, with a full load and refueling - two hundred and sixty-three tons. In order to raise such a "machine", we need engines of appropriate power. They were created by well-known machine-building companies. Requirements for the developed traction and reliability were very high. To date, the Boeing 777 installed several modifications of the engine, which are determined by the specific requirements of the customer.
The cabin can accommodate from 386 to 550human. This number depends on the equipment and the number of salons. If the Boeing 777 is equipped with salons of three classes, passenger loading is minimal. In the event that on board there are cabinets of business class and economy class, 479 passengers can fly to the flight. Loading to the maximum is possible in the case when all seats have the same, economical level of comfort. At the same time, the main crew consists of two or three people. Such minimalism became possible only as a result of high reliability of power units and the entire on-board control system.
The reliability of aircraft is given tothe most careful attention, including from licensing services. Boeing 777 is equipped with two turbojet engines. In the event that one of the engines fails, the aircraft will continue to fly to the alternate aerodrome for another three hours. In general, the maximum duration of the flight of the liner is more than fifteen thousand kilometers. In this regard, it should be noted that the modernization and improvement of the aircraft is constantly, and its technical characteristics are changing to a better level. In the test mode, the flight range has already reached the mark of 20,000 km.
Boeing 777, the photo of which makes an impressionits scale, demanded from the designers of maximum tension. All knowledge, intuition and experience were directed at solving various local problems. One of them was to make it as light as possible. To achieve this goal, composite materials were created and applied that had the required characteristics. Particularly discussed the design of the chassis. And the solution was found very simple and effective. That's how the result turned out to be the most advanced and comfortable aircraft for today.
