Note (General): Research and development to increase reliability of rocket engines, such as LE-7A and LE-5B, were conducted in the present study. Amplitude of turbopump rotor vibration due to rotating cavitation was suppressed by modification of inducer design and optimization of inducer liner geometry. Cryogenic inducer test facility to investigate various aspects of inducer performance in cryogenic fluids was newly constructed. Tests of a cryogenic inducer have been conducted. Excessive lateral thrust of LE-7A engine during start and stop transients was investigated to find a method to suppress it. Low cycle combustion pressure oscillation encountered in the LE-5B engine was also investigated to suppress the oscillation.
