Abstract

The invention relates to a four-rotor aircraft and a control system thereof. The four-rotor aircraft comprises a rack, a first shaft, a second shaft, a third shaft, a fourth shaft, a first rotor, a second rotor, a third rotor, a fourth rotor, a first rotor shaft, a second rotor shaft, a third rotor shaft and a fourth rotor shaft. The first rotor shaft deflects in the axial direction of the first shaft, the second rotor shaft deflects in the axial direction of the second shaft, the third rotor shaft deflects in the direction of the third shaft, and the fourth rotor shaft deflects in the axial direction of the fourth shaft. The flying direction of the aircraft can be changed by adjusting the deflecting angles of the rotor shafts, and therefore the flying direction of the aircraft can be controlled conveniently.

Description

technical field [0001] The invention relates to the field of aircraft, in particular to a quadrotor aircraft and a control system thereof. Background technique [0002] Quadrotor aircraft has the advantages of vertical take-off and landing, hovering in the air, etc., and is widely used. However, the existing quadrotor aircraft changes the flying attitude of the aircraft in the air by adjusting the speed of the four rotors. It has poor crosswind resistance and slow attitude adjustment. and other defects. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a four-rotor aircraft with strong crosswind resistance and sensitive flight direction adjustment. [0004] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: a quadrotor aircraft, which includes a frame, a first shaft, a second shaft, a third shaft, a fourth shaft, a first rotor, a second rotor, a third rot...
