PROPELLER ASSEMBLY, POWER SYSTEM, AND AERIAL VEHICLE

WIPO Patent Application WO/2018/045575

A1

A propeller assembly, a power system, and an aerial vehicle. The propeller assembly (13) comprises first propellers (131) and second propellers (132) that are disposed at intervals. Each first propeller (131) comprises a first propeller hub (1311) and at least one first blade (1312) connected to the first propeller hub (1311). Each second propeller (132) comprises a second propeller hub (1321) and at least one second blade (1312) connected to the second propeller hub (1321). During the rotation of the propeller assembly (13), acceleration air flows generated duration the rotation of the first propellers (131) point to the second propellers (132) from the first propellers (131) and act on the second propellers (132), so that the radial attack angle line types of the second blades (1322) are different from those of the first blades (1312). In this way, the radial attack angle line types of the blades on different layers are set to be different from each other, and accordingly the impacts of difference between air flow speeds among the blades on different layers to the working effects of the propellers can be effectively avoided.
