vasily sevastyanov claims to ms-21. no, everything is fine.bove all praise , a very wonderful aircraft for passengers and for the crew, everything is very ergonomically verified, a distinctive feature of the liner is wings made of composite materials, in order to have a pleasant effect on aerodynamics in terms of strength, the composite is not inferior to metal, but much easier back in 2018. when the americans realized that boeing had a strong competitor, they banned us from supplying high-tech carbon fiber for a couple of years. we learned how to make it ourselves and even outperformed the competition, which has a prefabricated wing made up of different parts. and here it is manufactured entirely at the plant in ulyanovsk , our e, furnace, which we use much cheaper and consume much less energy. well, the complexity of manufacturing prefabricated structures is much higher than the labor-intensive representation of the integral. this is all money. this is all the cost of manufacturing the wing. well , then it affects the cost of the aircraft. n
