COUNTER-ROTATIONAL INERTIAL CONTROL OF ROTORCRAFT

摘要

A rotorcraft with two counter-rotating rotors and method for inertially controlling the rotorcraft. The rotorcraft includes a hinged frame configured such that at least one inter-rotor angle of the two counter-rotating rotors is controlled by at least one actuated hinge of the hinged frame and the rotational axes of the two counter-rotating rotors are substantially collinear when the actuated hinge is in a fully open position. The sum of the magnitudes of torque applied to the two counter-rotating rotors is varied to control the lift of the rotorcraft. The difference of the magnitudes of torque applied to the two counter-rotating rotors is varied to control the yaw of the rotorcraft. The at least one inter-rotor angle is varied using the at least one actuated hinge to control the pitch and/or roll of the rotorcraft.
