Vector-boost multi-rotor unmanned aerial vehicle structure

Abstract

The invention discloses a vector-boost multi-rotor unmanned aerial vehicle structure comprising a main vehicle and a plurality of rotor assemblies. Each rotor assembly is connected with the main vehicle through a corresponding main vehicle support. The rotor assemblies are arranged around the main vehicle in an encircling mode. A steering engine is arranged on each main vehicle support. The steering engines are connected with deflection-type motor fixing seats of the rotor assembles connected on the main vehicle frame through steering engine connecting rods. Motors and propellers are arranged on the deflection-type motor fixing seats. The steering engines can adjust the angles of the deflection-type motor fixing seats connected with the steering engines and the propellers arranged on the deflection-type motor fixing seats. The postures of the propellers of an unmanned aerial vehicle are changed by using the steering engines (servers), so that vector rotors are controlled in a mode of changing the tensile direction of the rotors on the basis of adjusting the rotating speed, the control effect is better than a traditional multi-rotor unmanned aerial vehicle, the controllability and flexibility of the unmanned aerial vehicle are improved, in addition, electric energy is better saved, and the endurance ability of the unmanned aerial vehicle is indirectly improved. The vector-boost multi-rotor unmanned aerial vehicle structure can be applied to the fields of aerial photographing unmanned aerial vehicles and the like.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a vector propulsion multi-rotor unmanned aerial vehicle structure. Background technique [0002] There are three common UAV structures: fixed-wing, multi-rotor and autogyro, which are used in different fields according to their control principles and characteristics. Among them, multi-rotor drones can be divided into four-rotor, six-rotor, eight-rotor and other types according to the number of rotors. Its biggest feature is that it has multiple pairs of rotors, and the steering of each pair of rotors is the same, which is used to offset each other. Counter torque torque. Compared with other unmanned aerial vehicles, multi-rotor drones have unique advantages. Compared with fixed-wing aircraft, it has the advantages of vertical take-off and landing, and can hover at a fixed point; compared with single-rotor helicopters, it has no tail rotor device, so It has the advantages ...
