The invention provides an air propeller and a high-altitude long-endurance unmanned aerial vehicle applying the air propeller, the air propeller comprises five blades, the blades are sequentially arranged along a rotating center shaft, each blade is sequentially provided with 12 stations from near to far in the blade spanwise direction, and airfoil profile space distribution information of each station is determined. According to the air propeller provided by the invention, the aerodynamic efficiency under multiple working conditions is considered, the air propeller has enough takeoff and climbing thrust, and the aerodynamic resistance can be effectively reduced and the efficiency of the propeller can be improved on the premise of ensuring the thrust requirement, so that the requirement on a power system when a high-altitude long-endurance unmanned aerial vehicle executes a task is ensured.
本发明提供了一种空气螺旋桨及应用该空气螺旋桨的高空长航时无人机,其中空气螺旋桨包括五片桨叶,各桨叶分别沿旋转中轴依序排布,各桨叶沿叶片展向由近至远依序设有12个站位,并确定了各站位的翼型空间分布信息。本发明提供的空气螺旋桨,兼顾了在多工况下的气动效率,具有足够的起飞、爬升推力,能够在保证推力要求的前提下,有效降低气动阻力,提高了螺旋桨的效率,从而保证了高空长航时无人机执行任务时对动力系统的需求。
