| Abstract: | In order to improve the propeller cavitation performance,the circulation distribution is determined through the tradeoff of the efficiency and cavitation.The influence from hub is included in the propeller design by the lifting surface theory.The blade surface geometry is completely specified by using a small number of control vertexes of the B-spline.The square summation of the normal velocity distribution calculated by the lifting surface theory at the control points on the blade surface is regarded as an objective function.The blade geometry can be obtained by minimizing objective function. |
