摘　　要：逆向工程技术可以实现产品的快速创新,将该技术应用到船用螺旋桨改型设计中,突破了螺旋桨的传统设计模式。通过对叶片数字化模型进行整体扭转变形和翘曲变形实现了桨叶的改型,并结合CFD计算,发现这种改型方法对提高螺旋桨的推进效率具有重要的作用。研究结果表明,扭转变形5°、10°和15°,其效率分别提高了4.3%、6.75%和9.42%。在扭转15°的条件下分别对叶梢翘曲±10 mm,发现翘曲-10 mm时推进效率略有降低,而翘曲+10 mm后推进效率有显著提高。The reverse engineering technology can achieve rapid product innovation, which is applied to modify the propellers in ships. The method breaks through the traditional design patterns of propellers. In the paper, the digital mold of the propeller is modified by torsional deformation of the entire leaf and warp deformation of the tip of propeller. It is found that the modification method plays an important role of improving the propulsion efficiency of the propeller. The results show that the efficiency of the propellers with the torsional deformation of 5°, 10° and 15° are improved by 4.3%, 6.75% and 9.42% respectively. The propeller tip with the torsional deformation of 15° is warped by ±10 mm. When the warp is-10 mm, the efficiency is reduced slightly. The efficiency of the propeller with the warp of 10 mm is improved significantly.
