The United Aircraft Corporation (UAC, part of the Rostec Group) has changed the range of the newest MC-21 civil aircraft - from 5100 kilometers to 3830 kilometers. Military pilot and retired Major General Vladimir Popov called for not considering such a measure a death sentence for the liner.
He explained that UAC has determined the guaranteed distance that this aircraft can cover. It is no coincidence that it is less than those indicators that the designers had previously laid down in the future liner.
If you load the aircraft with passengers and cargo, say, within 30-50%, take the maximum amount of fuel, then the aircraft will be able to reach up to 5 thousand kilometers.
Popov emphasized that this does not mean that domestic developments are worse. Developers, on the contrary, place increased requirements on systems and components. This is the difference between the approaches of Western and our designers.
We have such tolerances that the metal wall should be thicker and the strength should be higher. Designers usually lay down a force of 5-7 times, or even 10 times. Therefore, we get some structures or aircraft in general heavier. This must be known and not say that we have bad planes or we don't know how to do something. The ideology of the approach is different. And the schools are engineering, technological - different from us.
Let us remind you that at the end of October, the second experienced MC-21-310 aircraft in a import-substituted version took to the sky, but without replacing five important systems. Employees of the Irkutsk Aviation Plant worked around the clock to get the second test aircraft into the sky as soon as possible.
