摘　　要：为探究诱导轮叶片厚度对空化性能的影响,以液体火箭发动机的液氧涡轮泵为研究对象,采用改变叶根处厚度的方法,设计了4种不同叶片厚度的诱导轮,其中叶尖处的厚度随着叶根处厚度的改变而相应变化。针对这4种方案的诱导轮,进行了强度校核和空化性能分析。研究结果显示,在保证叶片强度的前提下,选择较薄的诱导轮有助于改善涡轮泵的空化性能,同时,叶尖处的厚度对涡轮泵的空化性能也有显著影响。To investigate the effect of inducer blade thickness on cavitation performance,the liquid oxygen turbopump of a liquid rocket engine is taken as the research object.Four inducers with different blade thicknesses are designed by changing the thickness at the blade root,and the thickness at the blade tip changes accordingly with the change in blade root thickness.Strength verification and cavitation performance analysis are conducted for the inducers of these four schemes.The research results show that selecting thinner inducers can improve the cavitation performance of turbopumps while ensuring blade strength.Meanwhile,the thickness at the blade tip also has a significant impact on the cavitation performance of the turbopump.
