Abstract

본 발명은 선박을 추진시키는 프로펠러에 관한 것으로, 특히 회전중인 프로펠러의 원주방향의 모든 날개들의 피치를 선박의 반류에 적합하게 함으로써 프로펠러의 종합적인 성능을 향상시킨 반류적합 산박용 프로펠러에 관한 것이다.The present invention relates to a propeller for propelling a ship, and more particularly, to a reflux-fitting mountain propeller that improves the overall performance of the propeller by making the pitch of all the wings in the circumferential direction of the rotating propeller suitable for the reflux of the ship.

본 장치는 프로펠러의 피치가 원주방향의 모든 위치에서 반류에 대해 최적상태를 유지함으로써 프로펠러의 각 날개 걸리는 부하가 거의 일정하고, 이에 따라 프로펠러축의 진동이 감소되어 캐비테이션이 줄어 든다. 더욱이, 캐비테이션이 감소함에 따라 캐비테이션으로 인해 유발되는 제 현상들인 기진력과 소음도 현저히 감소하는 특징을 갖는다. 따라서, 프로펠러의 효율이 증대될 뿐만아니라 프로펠러의 전반적인 성능이 향상되는 효과를 갖는다.The device maintains the optimum propulsion of the propeller at all positions in the circumferential direction against the return, so that the load on each wing of the propeller is nearly constant, thereby reducing the vibration of the propeller shaft and reducing cavitation. Moreover, as cavitation decreases, vibration and noise, which are the phenomena caused by cavitation, are also significantly reduced. Therefore, not only the efficiency of the propeller is increased but also the overall performance of the propeller is improved.
