A composite propeller cavitation performance calculation method. The present invention relates to a composite material propeller cavitation performance calculation method. In order to solve the problem that due to generation of cavitation, the existing method will affect hydrodynamic performance of propellers, reduce propulsion efficiency, severely affect concealment of vessels, corrode surface materials of the propellers and cause surface material defects, the present invention provides a composite material propeller cavitation performance calculation method. The method comprises: establishing a geometric model; carrying out grid division; carrying out structure and fluid arrangement; carrying out structure and fluid calculation; exporting a deformed geometric model; re-dividing a grid; and carrying out cavitation performance calculation. The method provided by the present invention is applied to the field of propellers. 种复合材料螺旋桨空泡性能的计算方法，本发明涉及复合材料螺旋桨空泡性能的计算方法。本发明是要解决现有方法会因产生空泡影响螺旋桨的水动力性能，降低推进效率，严重影响舰船的隐蔽性，剥
