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.
