Abstract

The utility model provides a kind of high-efficiency propeller and unmanned aerial vehicle, including hub, with the hub connection blade, the installation angle β between the blade from 0.16±0.005L any position to blade tip is decreased from 25.2°±0.3° to 3.83°±0.3°;Wherein, L is the distance from the hub center axis to blade tip.In this scheme, the end of the blade away from the hub is the blade tip, the end close to the hub is the blade root, the arbitrary position of the blade 0.16±0.005L is the part of the blade close to the hub / blade root end.The installation angle β is also pitch angle, the included angle between the straight line direction of the leading edge and the trailing edge of the blade section and the rotating plane is pitch angle.Setting the installation angle of the blade can reduce the speed, reduce power, improve force efficiency under the same pull force as traditional blade.
