Abstract

The invention relates to the technical field of unmanned aerial vehicles, and specifically discloses a blade, a propeller and an unmanned aerial vehicle. The blade of the present invention includes a blade body and a winglet, the winglet includes a flat plate portion and a connecting portion, the winglet is arranged at the first end of the blade body, and the blade The main body, the connecting portion, and the flat plate are connected in sequence to form a continuous smooth curved surface. From the first end to the flat plate, the width of the smooth curved surface gradually decreases, and the winglet There is an inclination angle α with the blade main body in the horizontal direction, 10°≤α<35°. The blade adopts the layout design of winglets, which improves the aerodynamic performance and dynamic characteristics of the propeller, reduces air resistance, improves efficiency, improves the flight speed and flight distance of the unmanned aerial vehicle; and reduces disturbance The influence of the flow on the wing tip improves the control performance of the propeller and improves the flight stability of the unmanned aerial vehicle.

Description

【Technical field】 [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a blade, a propeller and an aircraft. 【Background technique】 [0002] The propeller is a power component that generates the lift, pulling force and operating force necessary for the flight of an unmanned aerial vehicle. Improving the efficiency of the propeller can greatly improve the flight performance of the unmanned aerial vehicle. [0003] The existing propellers have low efficiency and poor stability, resulting in low flight speed, short cruising distance and poor flight stability of unmanned aerial vehicles. 【Content of invention】 [0004] The present invention aims to overcome the defects of low propeller efficiency and poor stability in the prior art unmanned aerial vehicle, and provides an improved propeller blade, a propeller and an unmanned aerial vehicle using the propeller blade. [0005] In order to solve the above technical problems, the prese...
