An apparatus for enhancing propulsion efficiency is disclosed. The apparatus for enhancing propulsion efficiency, according to an embodiment of the present invention, comprises: a pre-swirl stator which is arranged in the front of a propeller; and a winglet which is formed in the end of the pre-swirl stator to be bent to a suction surface or a pressure surface. Therefore, the present invention reduces cavitation generated in the end of the pre-swirl stator.

    추진효율향상장치가 개시된다. 본 발명의 실시예에 따른 추진효율향상장치는 프로펠러의 전방에 배치되는 전류고정날개를 포함하고, 상기 전류고정날개의 끝단부에는 흡입면 또는 압력면 쪽으로 꺾인 윙렛(winglet)이 형성될 수 있다.
