CYCLOID ROTOR AND METHOD OF FORMING LIFTING OR PROPULSIVE FORCE Russian patent published in 2021 - IPC B64C27/59 B64C11/32 

FIELD: machine building.

SUBSTANCE: cycloid rotor comprises multiple blades installed to follow in common non-circular guide, means of changing said guide, made with possibility of transition between multiple forms of guides; means to control pitch of blade for adjustment of angle of attack of blade, facilities providing dynamic balance for blade to ensure that rotor remains balanced. Drive means are provided to allow the blades to move along the guide. Method of forming lifting or propulsive force includes providing cycloid rotor blades installed on non-circular guide, having means for changing the shape of the guide for movement along the corresponding non-circular orbit; providing an automated control system operatively connected to means of changing the shape of the guide for monitoring the position of means of retaining blades and drives for varying the angle of attack of the blades; providing drive mechanism for movement of blades along guide; rotation of blades along orbits at speed suitable for formation of lifting or propulsive force. Provided is control of automated control system for activation of actuators, responsible for change of angle of attack relative to blade position on guide, and means of changing the shape of the guide to achieve an optimum blade trajectory.

EFFECT: group of inventions is aimed at eliminating problems with stability during aircraft horizontal flight due to incident flow, which breaks flows produced inside rotor.
