Abstract

The invention discloses a rotor wing structure applied to an unmanned aerial vehicle, belonging to the technical field of unmanned aerial vehicles. The rotor wing structure comprises a first rotor wing, and a first rotating blade of the first rotor wing is fixedly connected with a first rotor wing shaft of a steering engine; a first weight balancing block is fixedly connected with the first rotorwing shaft, and a first rotating blade and the first weight balancing block are symmetrically arranged relative to the first rotor wing shaft; a second rotating blade of a second rotor wing is fixedlyconnected with a second rotor wing shaft of the steering engine; the second weight balancing block is fixedly connected with the second rotor wing shaft, and the second rotating blade and the secondweight balancing block are symmetrically arranged relative to the second rotor wing shaft. A first driving motor comprises a first driving shaft and a driving and fixing seat; tail spin seats are fixedly arranged on two sides of a second and / or fourth tail side surfaces, and the driving and fixing seat is arranged on the tail spin seat and / or a third body; a third steering engine comprises a thirdrotor wing shaft and a third fixing seat; a linkage part comprises a first joining end, a second joining end and a tail rotor wing. The rotor wing structure has the technical effects that pushing force and pulling force are supplied for the unmanned aerial vehicle to take off and land as well as to fly in the whole journey, the rotor wing structure is simple, and the maintenance is convenient andfast.

Description

technical field

[0001] The invention belongs to the technical field of unmanned aerial vehicles, in particular to a rotor structure applied to unmanned aerial vehicles. Background technique

[0002] Unmanned UAV, referred to as "UAV", is an unmanned UAV controlled by radio remote control equipment and its own program control device. The rotor is the main lift component of the UAV. During the flight of the UAV, the rotor plays a role in generating lift.

[0003] Currently, rotors are made up of multiple (more than 2) blades, and as the blades in the rotor rotate, the blades will interact with the surrounding air, creating a pulling force along the rotor axis that will give the aircraft an upward movement of lift. By adjusting the rotation speed of the blades, the magnitude of the lift is controlled, so that the aircraft can take off and land. At the same time, before the UAV leaves the factory, the rotor is often installed on the top of the UAV. When the blades in the roto...
