The invention discloses a fin stabilizer with bulge front edges, which relates to the technical field of marine equipment, and mainly structurally comprises a fin stabilizer body. A plurality of bulgefront edges protruding forwards are arranged at the front end of the fin stabilizer body. The fin stabilizer with the bulge front edge is simple in overall structure, and on the premise that a control and transmission mechanism is not additionally arranged, the flow field structure can be improved, the hydrodynamic performance of the fin stabilizer can be improved, and the stability of a ship canbe improved no matter whether the fin stabilizer is manufactured into a retractable fin stabilizer or a non-retractable fin stabilizer; the oval front edge or curvature continuous front edge blade profile can reduce cavitation erosion and effectively prolong the service life of the fin stabilizer; the front edge protruding forwards is combined with the fin stabilizer body in an oval transition mode, or the front edge protruding forwards is combined with the fin stabilizer body in a curvature continuous transition mode, fin stabilizer resistance during advancing can be reduced, and therefore oil consumption is reduced, and economic benefits are improved.
本发明公开一种带鼓包前缘的减摇鳍,涉及船用设备技术领域,主要结构减摇鳍本体,所述减摇鳍本体的前端设置有多个向前凸起的鼓包前缘。本发明中的带鼓包前缘的减摇鳍,整体结构简单,无论是制成收放式减摇鳍,还是非收放式减摇鳍,都能够实现在不增加控制和传动机构的前提下,改善流场结构,提升减摇鳍的水动力性能,改善船舶的稳定性;椭圆型前缘或曲率连续型前缘叶型可减少空泡侵蚀,有效延长减摇鳍使用寿命;向前凸起的前缘与减摇鳍本体椭圆形过渡结合,或向前凸起的前缘与减摇鳍本体曲率连续型过渡结合,能够降低前进时的减摇鳍阻力,从而降低油耗,提高经济效益。
