Japanese Patent JP6995354
Kind Code:
B2
Abstract:
To be able to improve sufficiently propulsion efficiency by simultaneously realizing a rectification effect and a thrust generation.SOLUTION: A stator fin (20) generates a swirling flow in the inverse direction of the rotational direction of a propeller, and comprises port side fins (21A, 21B) to rectify a flow around the stern downward and starboard side fins (21D, 21E) to rectify a flow around the stern upward, and is configured such that the camber direction at the base end side and at the tip side of the port side fins and of the starboard side fins is reversed.SELECTED DRAWING: Figure 5
