The invention provides an air propeller applied to a short-distance take-off and landing unmanned aerial vehicle, the air propeller comprises a rotating center shaft and three blades, and the three blades are arranged around the rotating center shaft at an interval of 120 degrees; and each paddle is sequentially provided with ten stations from the connecting end to the open end along the radial direction of the paddle. According to the implementation mode, through multi-target coupling optimization design, the aerodynamic efficiency of the air propeller under multiple working conditions is considered. Besides, according to the short-distance take-off and landing requirements of the unmanned aerial vehicle, propeller reversing function design is carried out while propellers have large enough take-off lift force, the unmanned aerial vehicle can be helped to generate high resistance during landing, the taxiing distance of the unmanned aerial vehicle is effectively shortened, and landing safety is improved.
本发明提供了一种应用于短距起降无人机的空气螺旋桨,包括旋转中轴和三个桨叶,其中,三个桨叶环绕所述旋转中轴间隔120°设置;每个桨叶沿该桨叶的径向由连接端到开放端依次布置10个站位。该实施方式通过多目标耦合优化设计,兼顾了空气螺旋桨在多工况下的气动效率。此外,针对无人机短距起降需求,在螺旋桨具备足够大的起飞升力同时进行了反桨功能设计,着陆时可帮助无人机产生较高的阻力,有效降低无人机滑跑距离并提高着陆安全性。
