Title:
PROPELLER, POWER ASSEMBLY AND AIRCRAFT
Document Type and Number:
WIPO Patent Application WO/2019/019332
Kind Code:
A1
Abstract:
Disclosed are a propeller, a power assembly and an aircraft.A propeller (100) comprises a propeller hub (10) and a propeller blade (20), the propeller blade (20) being connected on the propeller hub (10). At a distance of 40% of the radius of the propeller (100) from the centre of the propeller hub (10), the angle of attack of the propeller blade (20) is 16.98° ± 2.5°, and the chord length of the propeller blade (20) is 22.6 mm ± 5 mm. At a distance of 60% of the radius of the propeller (100) from the centre of the propeller hub (10), the angle of attack of the propeller blade (20) is 13.99° ± 2.5°, and the chord length of the propeller blade (20) is 17.59 mm ± 5 mm. At a distance of 80% of the radius of the propeller (100) from the centre of the propeller hub (10), the angle of attack of the propeller blade (20) is 11.78° ± 2.5°, and the chord length of the propeller blade (20) is 12.7 mm ± 5 mm. The present invention can optimise the structure of a propeller, increasing flight performance of an aircraft.
