The main feature of the import-substituted MC-21 aircraft is a fully composite wing, thanks to which the aircraft will gain an advantage in fuel efficiency. This was stated by Anatoly Gaidansky, Deputy General Director of the Yakovlev company (part of the United Aircraft Corporation of Rostec).
According to him, over time, domestic aircraft will begin to win in weight when they accumulate the necessary experience in the operation of this material.
Unlike metal, composite is not subject to corrosion and does not have fatigue damage. This is an infinite resource. I am absolutely sure that composite materials have a future in civil aviation, and now our competitors are closely watching aircraft of the same class, which, most likely, will also have composite wings, possibly composite fuselages.
The MC-21 wing was created from polymer composite materials of domestic production. It was developed in a short time after the introduction in 2018 of restrictions on the supply of foreign raw materials for the production of composites.
Earlier, www1.ru reported that by 2030, Russia will build almost 1,000 aircraft for civil aviation.
