At the Central Aerohydrodynamic Institute named after Professor N.E. Zhukovsky (TsAGI), research has been completed on the configuration options for a new aircraft for mainline passenger transportation of 220–250 passengers over a range of up to 10,000 km. This was announced by Academician of the Russian Academy of Sciences, Scientific Director of TsAGI, Sergei Chernyshev.
According to him, engineers have identified a configuration with an oval fuselage in cross-section, a mid-mounted wing, and an integral leading-edge extension between them as the optimal design.
This leading-edge extension participates in creating lift and is more advantageous from an aerodynamic point of view. It also provides a greater structural height in the root section of the wing, which allows increasing its elongation.
At the same time, the additional volumes inside the leading-edge extension allow accommodating the landing gear and many functional systems of the aircraft.
At the same time, the flattened fuselage design has reduced drag. This creates an internal volume for comfortable accommodation of passengers on the upper deck and cargo on the lower deck. This configuration allows carrying 45% more payload than two compartments in the classic version.
Chernyshev clarified that traditional "tube with wing" schemes are giving way to integrated ones, where the boundary between the fuselage and the wing is blurred. In engineering jargon, such schemes are called "flying wing."
