Document Type and Number:
WIPO Patent Application WO/2018/188486
Kind Code:
A1
Abstract:
Provided are a propeller and propulsion system thereof; a propeller (100) comprises a cylindrical body (101) forming a fluid channel (105), and a propulsion shaft (102) rotatably arranged inside said fluid channel (105). The propulsion shaft (102) is configured such that a spray fluid moving from a first end (301) to a second end (302) is formed in the fluid channel (105). The propulsion shaft (102) has a connecting part (201) used for providing a fixed point connected to a propelled device, and a power part provided with a blade (202); the power part is connected to the connecting part (201), and the blade (202) extends continuously in the direction from the connecting part to the power part. The propulsion system having said propeller has the advantages of a high thrust-to-weight ratio, a simple structure, stable and reliable operation, and energy efficiency and high effectiveness.
