AIRCRAFT Russian patent published in 2022 - IPC B64C27/22 B64C29/00 

FIELD: aircraft engineering.

SUBSTANCE: invention relates to the field of aviation, in particular to the designs of rotary-wing aircraft. The aircraft contains a fuselage, bearing planes, a tail, a pushing propeller placed on the tail end of the fuselage, or a pulling propeller on the nose end of the fuselage, or a jet engine. The pusher propellers are placed with support on the elements of the airframe of the aircraft in such a way that the propellers are located under the airframe of the aircraft. At the same time, the planes of their rotation are assigned below the airframe of the aircraft and are oriented horizontally. The propellers located under the airframe of the aircraft are shifted from the surface of the airframe elements, with the support on which they are located, at a distance of at least 15% of the diameter of the propellers.

EFFECT: high weight and energy efficiency is provided.
