The dynamic response of the cavitating LE-7 liquid oxygen (LOX) pump, which is essential for POGO analysis of the H-II rocket, was determined by generating sinusoidal flow perturbation with a slit-type perturbation valve installed in the main pump discharge line. In a study of suppressing the LE-7 LOX turbopump rotor vibration due to cavitation, it was found that a kind of rotor vibration, thought to be caused by rotating cavitation, disappeared when a certain geometry of inducer housing was used. Therefore, the effects of inducerhousing geometry on cavitation compliance and on the mass flow gain factor were investigated. Comparison of the test results showed that cavitation compliance for the geometry in which the rotor vibration due to rotating cavitation disappeared was much larger than that for the geometry in which the rotor vibration existed.
