The invention discloses a high-performance ducted propeller. The propeller comprises paddles, a hub, a rotary shaft and a duct, wherein the paddles and the hub adopt an integrated structural design; a shaft hole is formed in the hub; the hub is connected with the rotary shaft by a flat key; the duct is fixedly installed on a hull, and a gap exists between the inner wall of the duct and the outer edge of each paddle; and the duct adopts a conical barrel structure, and a sealing plate structure is arranged at the tail end of the duct. The invention provides a high-performance ducted propeller, and the propeller is reasonable in structural design and unique in effect; and the duct adopts the conical barrel structure, and the structure is beneficial to improving the flow-restraining effect and the stability of the duct, so that a ship propeller is more stable in working.
