Impeller blade tip end wing of water-jet propeller

The invention relates to the technical field of naval vessel propulsion, and discloses a water-jet propeller impeller blade tip end wing which comprises an original impeller blade tip and an end wing body, the end wing body is arranged at the original impeller blade tip, a blade root fillet is arranged at the joint of the end wing body and the original impeller blade tip, and an outer edge fillet is arranged at the end, not connected with the original impeller blade tip, of the end wing body. The end wings are additionally arranged at the blade tips of the impeller, on the premise that the power capability of the blade tips of the impeller is not changed, the effect of restraining or adjusting the gap flow of the blade tips is achieved, cavitation bubbles are delayed, the cavitation bubble performance of the propeller is improved, and cavitation bubble radiation noise is reduced. 本发明涉及舰艇推进技术领域，公开了一种喷水推进器叶轮叶梢端翼，包括原始叶轮叶梢和端翼，所述端翼设在原始叶轮叶梢处，且所述端翼与原始叶轮叶梢连接处设有叶根圆角，所述端翼未与原始叶轮叶梢连接的一端设有外缘圆角。本发明通过在叶轮叶梢处增加端翼，在不改变叶轮叶梢做功能力
