All brochures and descriptions specifically state that the Boeing 777 is completely designed using computer programs. Journalists and fans of information technology emphasize the fact that not a single graphic document was created during the design and production of the aircraft. All detailing and assembly sketches were compiled 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 almost ten years.
By its size, the Boeing 777 is considered the largest among civil aircraft. Its length is almost seventy-four meters, and the diameter of the fuselage is more than six meters. Weight at takeoff, fully loaded and refueled - two hundred and sixty-three tons. In order to raise such a "colossus", you need engines of appropriate power. Well-known engineering companies worked on their creation. The requirements for developed traction and reliability were very high. To date, several engine modifications are installed on the Boeing 777, which are determined by the specific requirements of the customer.
The cabin of the liner can accommodate from 386 to 550 people. This number depends on the equipment and the number of salons. If the Boeing 777 is equipped with three classes of cabins, the passenger load is minimal. In the event that there are business class and economy class cabins on board, 479 passengers can fly. Maximum loading is possible when all seats have the same economical comfort level. In this case, the composition of the main crew is two to three people. Such minimalism became possible only as a result of the high reliability of the power units and the entire onboard control system.
Issues of aircraft reliability are given the closest attention, including by licensed services. The Boeing 777 is equipped with two turbojet engines. In the event that one of the engines fails, the aircraft will continue flying to the alternate airfield 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.
Boeing 777, whose photos impress with their scale, demanded maximum effort 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. For achievementFor this purpose, composite materials were created and applied that had the required characteristics. Chassis design was discussed in particular. And the solution was found very simple and effective. This is how the most advanced and comfortable aircraft to date turned out to be.
