Problems solved by technology

When conventional multi-rotor plant protection drones perform agricultural plant protection and fertilization operations, if there are obstacles on the border of the area in the flight direction of the operation, in order to avoid the obstacles, it is necessary to keep a certain safe distance between the aircraft rotor and the obstacles, which will lead to areas near the border For the problem of not being able to work, sometimes it is necessary to use other means to supplement spraying, resulting in low work efficiency

Abstract

The invention relates to a six-axis heterogeneous multi-rotor-wing plant protection unmanned aerial vehicle and a rotor wing layout and control method thereof. The vehicle comprises a machine body, aundercarriage, four machine arms, motors and rotor wings, wherein the motors and the rotor wings are arranged on the machine arms, the four machine arms comprise two long machine arms and two short machine arms, each long machine arm is provided with two motors and two rotor wings, and each short machine arm is provided with one motor and one rotor wing. The invention further relates to the specific rotor wing layout method and rotor wing control method. The method can be applied to the field of agricultural aviation plant protection, and has large effective spraying amplitude and improves theoperation efficiency relative to a conventional equal-radius-configuration large-load plant protection unmanned aerial vehicle, the reduction influence of the front rotor wings on the efficiency of the rear rotor wings is reduced, and the energy utilization rate is improved.

Description

technical field [0001] The invention relates to the field of aircraft technology, in particular to a six-axis heterogeneous multi-rotor plant protection drone and its rotor layout and control method. Background technique [0002] UAV is a general term for unmanned aerial vehicles. It is equipped with autopilot, program control device and other equipment, and can be operated and controlled by ground station terminal or remote control. Compared with manned aircraft, it has the advantages of small size, low cost, and convenient use. It can take off vertically, take off and land automatically, and can be used repeatedly. It has been widely used in various industries. [0003] At present, for multi-rotor plant protection UAVs mainly used for spraying operations, in order to increase the load capacity and effective spraying range, longer arms and wheelbases are required, but the arms of conventional multi-rotor plant protection UAVs in the market are equal Long, when the aircraf...
