Seesaw-type tilt-rotor and aircraft thereof

Abstract

The present invention discloses a seesaw-type tiltrotor and an aircraft thereof, comprising a tilt mechanism installed at the end of a wing, a drive motor and a plurality of servos all installed on the tilt mechanism, the output end of the drive motor being coaxially connected to a main shaft, and an actuator cylinder being installed on the servo; a first action ring is coaxially sleeved on the main shaft and spaced apart from the tilt mechanism, and each first hinge structure on the first action ring is hinged to the piston rod end of each corresponding actuator cylinder; a second action ring is coaxially sleeved on a part of the first action ring away from the tilt mechanism, the second action ring is connected to the main shaft and rotates synchronously, the second hinge structure on the second action ring is connected to a torque change pull rod and a torque change rocker arm, and the other end of the torque change rocker arm is fixed on the blade assembly to realize the total pitch change and cyclic pitch change of the blade, and automatically adjust the inclination angle of the blade according to different flight states, provide higher stability and reliability, and can reduce the degree of damage to the central component caused by the flapping of the blade.
