All brochures and descriptions emphasize that the Boeing 777 is fully developed using computer programs. Journalists and information technology fans emphasize the fact that not a single graphic document was created during the design and production of the aircraft. All details and assembly sketches were made using programming and the use of computer graphics. Even the assembly of the aircraft was carried out in virtual space. All work on the design and production of a prototype lasted nearly ten years.
By its size
, the Boeing 777 is considered the largest among civilian aircraft. Its length is almost seventy-four meters, and the diameter of the fuselage is more than six meters. The mass on take-off, when fully loaded and refueling, is two hundred sixty-three tons. In order to raise such a “colossus”, engines of the corresponding power are needed. Well-known engineering companies worked on their creation. The requirements for developed traction and reliability were very high. To date, several modifications of the engine are installed on the Boeing 777, which are determined by the specific requirements of the customer.
The cabin liner can accommodate from 386 to 550 people. This amount depends on the equipment and the number of salons. If the Boeing 777 is equipped with salons of three classes, passenger load is minimal. In the event that there are business-class and economy-class salons on board, 479 passengers can fly. Downloading to the maximum is possible when all the places have the same, economical level of comfort. The composition of the main crew is two to three people. Such minimalism became possible only as a result of high reliability of power units and the entire on-board control system.
The issues of aircraft reliability are given the closest attention, including from the licensing services. The 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 flight duration 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 ongoing, and its technical characteristics are changing for the better. In test mode, the flight range has already reached 20,000 km.
The Boeing 777, the photo of which impresses with its scale, demanded maximum voltage from the designers. All knowledge, intuition and experience were aimed at solving various local problems. One of them was to lighten the weight of the aircraft as much as possible. To achieve this goal,
composite materials were created and applied that had the required characteristics. The design of the chassis was especially discussed. And the solution was found very simple and effective. This is how the result was the most advanced and comfortable aircraft to date.
