| 摘 要： | IntroductionIn the aerospace fields,flow induced vibrationswithin a rocket engine have a significant effect onrocket reliability.However,the development ofmodern high- performance rocket pump inducershas focuses mainly on the effects of rotatingcavitation.In a recentexperiment of a new type ofrocket engine,an oxygen pump inducer wasdestroyed.Analysis of the pump showed no pittingcaused by cavitation on the surface,but obliquefractures in the inlet blade.Figures 1 and 2illustrate the seriously…
