Two kinds of proplet, dihedral and anhedral proplet, are adopted to improve the aerodynamic efficiency of high-altitude propeller, and the effects of proplet geometric parameters are researched deeply. It concluded that proplet can improve the efficiency of propeller, and dihedral proplet can increase more aerodynamic efficiency than anhedral proplet of the same geometric parameters.
