METHOD OF CONTROLLING AERODYNAMIC MOMENTS OF COAXIAL HELICOPTER Russian patent published in 2024 - IPC B64C15/00 B64C27/10 

FIELD: aviation.

SUBSTANCE: invention relates to aircraft engineering, particularly, to control over coaxial helicopters. Coaxial helicopter has coaxial rotors with rotation drive, two tubular tail beams attached to the helicopter fuselage and spaced apart on different sides of the plane of symmetry of the helicopter, a jet control system including controlled nozzles located at the ends of the beams. Method of controlling aerodynamic moments of a coaxial helicopter includes creating a pitching moment by synchronous rotation of nozzles and/or changing the area of their output sections, roll moment by multidirectional rotation of nozzles and/or change of area of their output sections, yawing moment by changing the rotation frequency of the upper and lower coaxial rotors and/or multidirectional change of pressure or air flow rate through the nozzles of the left and right beams of the vehicle.

EFFECT: possibility of controlling pitching, roll and yawing moments of coaxial helicopters without using swash plates and other elements interacting with them, improving reliability, failure-free operation and service life.
