VTOL AIRCRAFT Russian patent published in 2023 - IPC B64C29/00 

FIELD: aircraft engineering.

SUBSTANCE: invention relates to the field of aircraft engineering. The VTOL aircraft comprises a fuselage having a nose section, a tail section and a middle section located between them, at least one keel located in the tail section of the fuselage. A gas turbine engine with a drive shaft located in the rear fuselage, the drive shaft is kinematically connected to the fan axles through the main gearbox and gearboxes. Fans installed in the middle part of the fuselage in such a way that they are able to create a flow of fluid from the hole in the upper part of the fuselage in the direction from the fuselage to the sides. The wings are designed in such a way that the lifting force is created by the fluid flow in the direction from the fuselage to the sides, the wings are connected to the motor shafts. Motors made with the ability to rotate the wings relative to the axis of the shafts in such a way that in one of the positions the wings are tilted forward, and in the other of the positions they are tilted back. A screen-exhaust device designed to reduce the temperature of the exhaust gases by mixing with atmospheric air entering the mixing chamber by creating a low-pressure area in it by passing a high-speed compressed air flow flowing from the nozzle apparatus and mixing the mixed flow with the incoming air in the exhaust channel flow. Devices of on-board radio-electronic equipment, made with the possibility of extension vertically upwards. Module of the vertical launch device with cells of the transport-launch container of guided missile weapons, located in the middle part of the fuselage. Fairings with channels made in them with a slot in such a way that they are able to create a fluid flow in the direction up and down from the fairing. Nozzles, in fairings, in the nose and tail of the fuselage, made with the ability to control the pitch, yaw and roll in all flight modes.

EFFECT: improvement of tactical and technical characteristics, in particular stealth and increase in the combat effectiveness of the aircraft.
