Aircraft and control method of aircraft

Abstract

The invention discloses an aircraft and a control method of the aircraft. The aircraft comprises an aircraft body, multiple aircraft arms and a power device, wherein the multiple aircraft arms are arranged in the periphery direction of the aircraft body at intervals, the end of each aircraft arm is connected with the aircraft body, at least one aircraft arm comprises a first rotating portion, oneend of the first rotating portion is connected with the aircraft body in a rotating manner so that the first rotating portion can rotate around the center axis of the aircraft body, and the power device is connected with the other ends of the aircraft arms and used for providing power for the aircraft. According to the aircraft, at least one aircraft arm comprises the first rotating portion, one end of the first rotating portion is connected with the aircraft body in a rotating manner so that the first rotating portion can rotate around the center axis of the aircraft body, and the posture ofthe aircraft can be adjusted more flexibly. In addition, by means of combination with the power device, in the flying process of the aircraft, the aircraft body of the aircraft is ensured to be horizontal, the air resistance is reduced beneficially, the aircraft can fly more rapidly, and hang time is prolonged.

Description

technical field [0001] The invention relates to an aircraft and a control method for the aircraft. Background technique [0002] The application of quadrotor aircraft is becoming more and more widespread. Quadrotor aircraft has good flexibility and simple requirements for take-off and landing sites. Therefore, quadrotor aircraft is widely used in the fields of aerial photography, plant protection, inspection and logistics. In related technologies, the speed, height and direction of the quadrotor are changed by controlling the output power of the four motors. For example, if the quadrotor flies forward, the output power of the two rear motors is increased. If the quadrotor is to turn, increase or decrease the output power of the diagonal pair of motors at the same time. [0003] However, the existing control method of the quadrotor is that the control of the attitude is not fine enough, and the speed of the quadrotor cannot be achieved very fast. In addition, controlling th...

[0003] However, the existing control method of the quadrotor is that the control of the attitude is not fine enough, and the speed of the quadrotor cannot be achieved very fast.

In addition, controlling the speed of the quadrotor by controlling the output power of the motor may become the performance bottleneck of the quadrotor in some fields. For example, when the current quadrotor moves in an arc in aerial photography, the attitude control of the fuselage is not fine enough. , and when the quadrotor accelerates, decelerates and turns, the fuselage of the quadrotor will tilt, which will also increase the difficulty of controlling the quadrotor gimbal, and if it is aerial photography, it will also reduce the quality of the video
