More Information
Summary:A propulsion efficiency enhancing apparatus is disclosed. According to an embodiment of the present invention, the propulsion efficiency enhancing apparatus comprises current fixing blades disposed in front of a propeller. The current fixing blades are located at regions wherein the propeller rotates upward, among the left region and right region of the surface of revolution of the propeller. Moreover, the span length of at least one of the current fixing blades is different from that of the current fixing blades, and the span length of a current fixing blade arbitrarily selected among the current fixing blades is greater than or equal to that of another current fixing blade disposed directly thereunder. 추진효율향상장치가 개시된다. 본 발명의 실시예에 따른 추진효율향상장치는 프로펠러의 전방에 배치되는 전류고정날개들을 포함하고, 상기 전류고정날개들은, 상기 프로펠러의 회전면의 좌측 영역 및 우측 영역 중 상기 프로펠러가 상방을 향하여 회전하는 영역에 위치하고, 상기 전류고정날개들 중 적어도 하나는 나머지와 스팬의 길이 상이하고, 상기 전류고정날개들 중 임의로 선택된 하나의 전류고정날개는 바로 아래에 위치하는 다른 전류고정날개 보다 스팬의 길이가 길거나 같다.
