The prospective Russian supersonic passenger aircraft will have an oval fuselage, not a round one like current airliners. This is stated in the documents for the research work "Integral" on the creation of prospective regional and mainline aircraft of a new generation.
The cross-section of the new generation aircraft will be oval, slightly flattened, not round like current ones.
The fuselage itself will partly act as a wing. This will require completely different design techniques, construction methods, and the formation of the power structure. The aircraft needs to be light; if it is strong but heavy, it won't take off.
According to him, it is no longer possible to improve already operating aircraft—technical progress in terms of power plants and layout schemes has already reached its maximum.
This often takes many years, decades, or even more than one decade. It is for this reason that real aircraft that will be created are likely to appear sometime in the 2040s.
Earlier www1.ru reported that Russia in aviation will be able to manage with its own developments: they didn't copy, but made it better.
