The invention relates to a deformation rudder blade with a self-adaptive deflection leading edge and a deflection method thereof. The deformation rudder blade comprises a rudder blade body and a deflection device; the rudder blade body comprises a first side wall, a second side wall and a leading edge wall, wherein the first side wall and the second side wall intersect to form a trailing edge; the two ends of the front edge wall are connected with the ends, away from the trailing edge, of the first side wall and the second side wall correspondingly, and the deflection device is arranged on the side, away from the trailing edge, of the front edge wall, used for changing the front edge deflection angle of the rudder blade and comprises a plurality of rudder layer deflection assemblies. The deflection assemblies are distributed on the side, away from the trailing edge, of the front edge wall at intervals in the length direction of the trailing edge. According to the deformation rudder blade with the self-adaptive deflection front edge and the deflection method of the deformation rudder blade, in a complex water body, the deflection angles of the multiple layers of deflection assemblies can be flexibly changed according to the actual inflow angles and the inflow speeds of the water body at different heights in the vertical direction; the front edge of the rudder blade can generate better hydrodynamic performance in a complex and non-uniform propeller rear wake flow field environment.

    本发明涉及一种自适应偏转前缘的变形舵叶及其偏转方法,该变形舵叶包括舵叶主体和偏转装置,舵叶主体包括第一侧壁、第二侧壁和前缘壁,第一侧壁和第二侧壁相交形成尾缘棱,前缘壁的两端分别与第一侧壁和第二侧壁远离尾缘棱的一端连接,偏转装置设置于前缘壁远离尾缘棱的一侧,用于改变舵叶的前缘偏转角度,偏转装置包括若干舵层偏转组件,若干偏转组件沿尾缘棱的长度方向间隔分布在前缘壁远离尾缘棱的一侧。本发明提供的自适应偏转前缘的变形舵叶及其偏转方法,在复杂的水体下,若干层偏转组件能够根据水体垂向不同高度的实际入流角与入流速度大小灵活改变偏转角度,实现舵叶前缘能够在复杂且不均匀的螺旋桨后尾流场环境中产生较好的水动力性能。
