摘　　要：在传统的螺旋桨升力面设计方法中,通常忽略径向诱导速度,将三维形式的边界条件简化成二维形式的边界条件,且在从随边到导边对速度积分求解拱弧线的过程中对边界条件作了简化处理。随着螺旋桨设计理论和计算方法的发展,采用更为严密的三维形式的边界条件成为可能。论文采用三维形式边界条件求解,开发了新的升力面设计程序,实现更严格意义上的三维设计。实例设计结果表明,对于具有较大纵倾的螺旋桨,采用三维形式边界条件进行理论设计可以更准确地反映桨叶的三维效应。In the published literatures of propeller lifting-surface design methods,2-D boundary condition is widely applied for simplification of the real 3-D boundary condition.Now,for the purpose of improving design precision,with the development of theory of propeller design and computational method,more precise 3-D boundary condition has been presented.In the paper,a new design method on propeller blade geometry based on 3-D boundary condition is developed.The new lifting-surface design method is established as the tool of processing boundary condition with the help of modern numerical method.The results of design examples show that more precise results could be got for propellers with large rake by the new method.
