ZERO FLIGHT AIRCRAFT Russian patent published in 2021 - IPC B64C29/00 

FIELD: aviation.

SUBSTANCE: invention relates to the field of aviation, in particular to the designs of vertical take-off and landing aircraft. A zero flight aircraft contains a fuselage and a carrier rotor mounted on it with blades connected to a mechanism for cyclically changing the angle of attack of the blades. The carrier rotor is made in the form of a drum, the axis of rotation of which is directed mainly along the direction of flight of the aircraft, and the blades are oriented with their length along the generatrix of the cylindrical lateral surface of the drum. The mechanism for cyclic variation of the angle of attack of the blades is made in the form of a crank mounted on a base stationary relative to the fuselage with the possibility of two-coordinate change of its position in the plane of rotation of the carrier drum. The device contains two devices for cyclic control of the angle of attack of the blades, connected to different sections of the length of each blade and with independent control channels.

EFFECT: invention provides increased reliability and service life of the carrier rotor mechanisms, a reduction in noise from the blades, and a reduction in the danger created by rotating parts.
