Title:
PROPELLER, POWER SET AND UNMANNED AERIAL VEHICLE
Document Type and Number:
WIPO Patent Application WO/2018/018729
Kind Code:
A1
Abstract:
A propeller, a power assembly and an aerial vehicle. The propeller comprises propeller blades (200). At a position on the blade (200) where a distance to the center of gyration of the propeller is 43.33% of the radius of gyration of the propeller, the angle of attack of the blade (200) is 27.4±2.5 degrees; at a position on the blade (200) where a distance to the center of gyration of the propeller is 62.59% of the radius of gyration of the propeller, the angle of attack of the blade (200) is 19.2±2.5 degrees; at a position on the blade (200) where a distance to the center of gyration of the propeller is 81.85% of the radius of gyration of the propeller, the angle of attack of the blade (200) is 14.1±2.5 degrees. The design of angles of attack for different portions of a blade reduces air resistance, improves the efficiency, and achieves a great propelling force.
