SHORT TAKE-OFF AND LANDING AIRCRAFT Russian patent published in 2020 - IPC B64C23/00 B64C39/00 

FIELD: aircraft; machine building.

SUBSTANCE: invention relates to the field of aircraft engineering, in particular, to development of cargo, passenger and multi-purpose aircraft of short take-off and landing, providing cargo-passenger transportation, rescue operations, and so forth in areas with underdeveloped aerodrome network and requiring shoulder transportation of more than 600…1000 km. In aircraft of short take-off and landing, comprising wing, fuselage, power plant and lines of fan-type propellers on deflectable flaps, for joint of wing with fuselage and arrangement of power plant additionally contains connecting fairing, made in form of small elongated profiled root wing with inclination angles of 10…60° of its lower and upper surfaces coupled with fuselage relative to horizontal plane, with relative profile thickness of 10…20 %. In the fuselage tail part there are two cantilevers forming V-shaped fins, and fuselage elevator, ahead of which there is an additional line of fan propulsors.

EFFECT: proposed aircraft ensures high bearing properties of wing in interaction with power plant at take-off and landing modes, reduction of front drag on cruise modes of flight and provision of high level of weight perfection of aircraft.
