Title:
NOISELESS BLOWER UNIT AND NOISELESS FLIGHT PROPULSION BODY COMPRISING NOISELESS BLOWER UNIT
Document Type and Number:
WIPO Patent Application WO/2023/249139
Kind Code:
A1
Abstract:
The disclosed noiseless blower unit comprises an air-core rotary disc member and a semispherical air-collecting member so that air flowing in through an open central portion of respective air-core discs constituting the air-core rotary disc member can be sprayed through centrifugal flow, and the air sprayed from the air-core rotary disc member is collected and jetted downward, while changing direction, along the outer surface of the semispherical air-collecting member, and thus the noiseless blower unit can intensively jet, without noise, air converging relatively more than the air flowing in through the open central portion of respective air-core discs, and can implement noiseless flight and also improve flight propulsive power if the noiseless blower unit is used for flight such that generated noise is remarkably reduced to be lower than that of a conventional flight propulsive power obtainment method in which propulsive power is obtained by rotating a propeller, and thus noiselessness can be implemented in ordinary flight space.
