WIPO Patent Application WO/2019/227268

A1

Provided are a propeller assembly (100), a power assembly (200) and an aircraft (1000). The propeller assembly (100) comprises a first paddle (10) and a second paddle (20), the first paddle (10) comprising a first paddle blade (11), and the second paddle (20) comprising a second paddle blade (21). The first paddle blade (11) comprises a first paddle root (111) and a first paddle tip (112) which extend away from each other, and a first paddle pressure face (113) and a first paddle suction face (114) which face away from each other; and the second paddle blade (21) comprises a second paddle root (211) and a second paddle tip (212) which extend away from each other, and a second paddle pressure face (213) and a second paddle suction face (214) which face away from each other. The first paddle tip (112) extends obliquely along a span direction of the first paddle blade (11) toward a side where the first paddle suction face (114) is located, and the second paddle tip (212) extends obliquely along a span direction of the second paddle blade (21) toward a side where the second paddle pressure face (213) is located. As such, the propeller assembly (100) can increase the pulling force and efficiency, and enables the aircraft (1000) to be quieter during hovering.
