Abstract:
A propeller (100), a power assembly (200), and an aircraft (1000); at a distance of 41.9% of the radius of the propeller (100) from the center of the hub (10), the angle of the propeller blade (20) is 25.65°±2.5°; at a distance of 53.5% of the radius of the propeller (100) from the center of the hub (10), the angle of the propeller blade (20) is 23.02°±2.5°; at a distance of 65.1% of the radius of the propeller (100) from the center of the hub (10), the angle of the propeller blade (20) is 20.68°±2.5°; at a distance of 76.7% of the radius of the propeller (100) from the center of the hub (10), the angle of the propeller blade (20) is 18.72°±2.5°; The propeller (100) using said propeller blade (20) can reduce air resistance, increase pulling force and efficiency, and increase the cruising distance of the aircraft in order to improve the flight performance of the aircraft (1000), and can also reduce the noise produced by the propeller blade (20) during operation, such that the aircraft is quieter when hovering, improving the user experience.
