Multi-rotor wing unmanned aerial vehicle, and system and flight control method thereof

Abstract

The invention provides a multi-rotor wing unmanned aerial vehicle, and a system and a flight control method thereof. The unmanned aerial vehicle comprises a machine frame and a horizontal driving device; a main rotor swing and a main rotor swing motor which is connected with the main rotor swing are arranged on the machine frame; the rotating axis direction of the main rotor swing is perpendicular to the horizontal plane of the machine frame; the horizontal driving device is arranged below the machine frame, and the direction of the driving force provided by the horizontal driving device is perpendicular to the rotating axis direction of the main rotor wing, wherein the main rotor wing motor and the horizontal driving device are both connected with a flight control board. No matter the multi-rotor wing unmanned aerial vehicle is in a hovering state or a running state, the attitude angle of the multi-rotor wing unmanned aerial vehicle is kept near zero all the time, and the problem of instantaneous height falling of the unmanned aerial vehicle caused by the inclining of the attitude angle can be avoided; the running power can be provided by the horizontal driving device without relying on the inclining of an attitude; therefore, the attitude of the unmanned aerial vehicle is stilled kept horizontally in the running process.

Description

technical field [0001] The invention relates to the technical field of multi-rotor UAV control, in particular to a multi-rotor UAV, its system and a flight control method. Background technique [0002] Multi-rotor drones have the characteristics of vertical take-off and landing, hovering in the air, take-off / landing without a runway, maneuverability and ultra-low altitude flight, etc., which make them have incomparable advantages over fixed-wing drones and have a wide range of application prospects. In terms of civil use, it can be used in agricultural plant protection, power line inspection, ambient air detection, traffic detection, water resource detection, aerial photography and disaster relief. In terms of military use, it can be used in mission reconnaissance, as a target drone, air relay, air / ground strike and jamming, electronic countermeasures and other fields. [0003] With the continuous development of multi-rotor UAVs in various fields, the tasks it performs are ...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a multi-rotor UAV and its system and flight control method to solve the problem that the existing multi-rotor UAV is not suitable for ultra-low-altitude flight due to the phenomenon of falling height when it advances and requires more accurate height occasional problem
