Electric multi-shaft tilt rotor unmanned aerial vehicle system

Abstract

The invention relates to an electric multi-shaft tilt rotor unmanned aerial vehicle system comprising a fixed-wing aircraft body and a flying controller achieving a stable control effect. A plurality of tilt rotors mounted on the aircraft body enable an aircraft to achieve the hovering function similar to that of a helicopter. According to the electric multi-shaft tilt rotor unmanned aerial vehicle system, the flying capacities of vertical takeoff and landing and high-speed cruise are achieved, free switching between a helicopter mode and a fixed-wing aircraft mode can be achieved, excellent manipulating stability, reliability and service safety are achieved, and the electric multi-shaft tilt rotor unmanned aerial vehicle system can be better applied to multi-point hovering detecting in a large-range area and can play a great role in diversified environments such as the land-based environment and the onboard environment, and military and civil application in the future.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to an electric multi-axis tilting rotor unmanned aerial vehicle system. Background technique [0002] Fixed-wing UAVs have the advantages of long range, low noise, and fast flight speed, but they are greatly affected by the take-off and landing environment and cannot hover in the air; rotary-wing UAVs can achieve vertical take-off and landing, low-altitude and low-speed flight, Hovering and other functions, but limited by its own structure, the load capacity is small, the noise is large, and the voyage is short. The combination of fast flight capability and vertical take-off and landing capability has undoubtedly become a research hotspot in the current UAV and even aircraft industry. [0003] At present, more and more research institutions in the world have begun to conduct research on tilt-rotor UAVs. However, for a typical dual-rotor tilt-rotor UAV, the rotor is installe...

AI Technical Summary

Problems solved by technology

However, for a typical dual-rotor tilt-rotor UAV, the rotor is installed at the tip of the wing, and the downwash of the rotor often causes serious aerodynamic interference, which increases the difficulty of UAV modeling and control; and because only With two rotors, each rotor needs to be installed with a variable pitch structure, resulting in a very complicated mechanical structure of the aircraft
