Abstract

The invention provides an unmanned aerial vehicle propeller and an unmanned aerial vehicle. The unmanned aerial vehicle propeller comprises blades, a propeller pedestal and at least two unmanned aerial vehicle blade connecting arms, the unmanned aerial vehicle blade connecting arms are fixed to the propeller pedestal, every unmanned aerial vehicle blade connecting arm comprises a blade supportingbody and a blade connector, the blade connectors are fixedly arranged on the blade supporting bodies, and are in rolling contact with the surfaces of the blade supporting bodies, connecting parts cooperating with the blades are arranged on one end parts of the blade connectors, and the blades are fixedly arranged on the connecting parts through first screws. The design of the rolling contact of the blade connectors on the unmanned aerial vehicle propeller and the blade supporting bodies realizes the adjustability of the blades, and the adjustability of the blades makes the flight direction ofthe unmanned aerial vehicle adjustable, so the problem of difficult flight control of unmanned aerial vehicles adopting existing unmanned aerial vehicle propeller structures is solved.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle propeller and the unmanned aerial vehicle. Background technique [0002] Existing multi-rotor UAVs use fixed-pitch propellers, and the pitch is not variable. The up and down movement of the aircraft depends entirely on adjusting the motor speed of each rotor, and the lift difference of each propeller is formed by the speed difference of each motor. Take a four-axis UAV as an example. Its upward motion is achieved by simultaneously increasing the speed of the motors on the four axes to generate lift, and simultaneously reducing the speed of the four motors during the downward motion. When moving forward, the rotation speed of the two motors at the back is increased to generate greater lift, which is achieved by generating a lift difference with the rotors on the two front axes, and the aircraft tilts forward to fly. This kind of control...
