Abstract

The invention discloses a four-shaft rotorcraft balance remediation device which comprises a rotorcraft body, wing columns, propeller blade rods, motors and propeller blades. The rotorcraft body is fixedly connected with the wing columns; each wing column and one end of the corresponding propeller blade rod are coaxially and rotationally connected; the other end of each propeller blade rod is rotationally connected with the corresponding motor; and output shafts of the motors are fixedly connected with the propeller blades. The four-shaft rotorcraft balance remediation device is simple in structure and ingenious in construction, and in combination with the bent propeller blade rods, the propeller blades rotate on the horizontal plane all the time, and lifting acting force is generated.

Description

technical field

[0001] The invention relates to the technical field of four-axis rotorcraft, in particular to a balance remedy device for four-axis rotorcraft. Background technique

[0002] The four-axis rotorcraft is that the four rotors are symmetrically distributed in the front, rear, left, and right directions of the body. The four rotors are on the same height plane, and the structures and radii of the four rotors are the same. The four motors are symmetrically installed on the bracket end of the aircraft. , the space in the middle of the bracket places the flight control computer and external equipment. By adjusting the rotation speed of the four motors to change the rotation speed of the rotor, the lift force can be changed, thereby controlling the attitude and position of the aircraft. Quadrotor aircraft is a vertical elevator with six degrees of freedom, but it has only four input forces and six state outputs at the same time, so it is an underactuated system. [...
