摘　　要：设计一种船用螺旋桨边界曲线改型方法,改型过程中通过移动导边侧约束面和随边约束面的位置来控制边界曲线的形状,从而实现螺旋桨的改型设计。通过Fluent软件模拟发现,随边侧约束面沿拉伸方向的移动可以有效提高螺旋桨推进效率,最高可以达到53.2%,而导边侧约束面的移动在一个相对较小的范围内对螺旋桨效率的提高也有明显的作用。A modification method of marine propeller boundary curve is created by the reverse engineering technique. In the method constraint faces at the leading edge and trailing edge of the propeller are moved to control the shape of the boundary curve, which can form a new marine propeller. Though the simulation of Fluent software, it shows that the propulsive efficiency of the propeller is significantly improved by moving constraint face at the trailing edge of the propeller. The maximum value is up to 53.2%. A relatively small range of the constraint face at the leading edge has obvious effect on improving the efficiency of propeller.
