The present invention provides a propeller assembly comprising: a propeller seat (12); the propeller blades (14) are arranged on the propeller seat (12) in a central symmetry manner; and a cap (16) disposed directly or indirectly on the propeller seat (12), each propeller blade (14) configured to have an air inlet, a cavity (35), and an air outlet (15), the air inlet and the air outlet (15) being respectively in fluid communication with the cavity (35), the air inlet being configured to receive air from the air inlet (20) of the propeller assembly, the air outlet being configured to receive air from the air outlet (20) of the propeller assembly, and the air outlet being configured to receive air from the air outlet (20) of the propeller assembly. The air outlet (15) is formed in the rear edge of the propeller blade (14) and used for discharging air entering the cavity (35) of the propeller blade (14). The propeller assembly can be self-driven to form an independent part and a self-formed system, overall arrangement of aircraft design is facilitated, the lift force is obviously increased compared with a conventional propeller, cost is low, the structure is simple, production is easy, and practicability is high.
本发明提供一种螺旋桨组件,包括:桨座(12);多个螺旋桨叶片(14),中心对称地设置在桨座(12)上;以及桨帽(16),所述桨帽(16)直接或间接地设置在桨座(12)上,每个螺旋桨叶片(14)被配置为具有进气口、空腔(35)和出气口(15),所述进气口和出气口(15)分别与空腔(35)流体连通,所述进气口被配置为接收来自螺旋桨组件的气体进口(20)的气体,所述出气口(15)设置在螺旋桨叶片(14)的后缘中,用于将进入螺旋桨叶片(14)的空腔(35)内的气体排出。本发明的螺旋桨组件能够自驱动,形成独立部件、自成系统,便于飞行器设计的总体安排,且升力较常规螺旋桨明显增大,成本低廉、结构简单、易于生产、实用性强。
