The latest Russian medium-range airliner MC-21 has received a unique domestic power supply system. This was announced by the chief aircraft designer Vitaly Naryshkin.
According to him, the aircraft and all its systems performed wonderfully during the test flight, and the pilots did not record any failures.
The aircraft is positioned as import-substituted, with PD-14 engines. It is important that we replaced the most complex power supply system, on which the operation of all other aircraft systems depends. It differs from all other domestic aircraft and many Western ones, except for the very latest, in that it can reconfigure itself in case of any failures and perform self-diagnostics.
Naryshkin noted that all this makes it possible to be confident in the reliability of the aircraft, and in the event of defects, to quickly eliminate the defect on the ground.
The system is new, no one in our country has ever done this before, it is built on computers and is half the size of the relay system in terms of dimensions and one and a half times in terms of weight. It is important that all radio-electronic equipment was replaced on the aircraft, and it did not cause any comments during the flight. We are gradually making the aircraft completely Russian.
Earlier www1.ru reported that there was a huge queue for import-substituted MC-21s, and the airliners will have to wait.
