Abstract:
The capability of turbo-pump working in variable conditions is required and important for pump—pressurized variable thrust rocket engine and ramjet propulsion．Combining with a test of the upper stage rocket engine，the performance and stability of the turbo-pump at low condition are studied in this paper．Through the full flow characteristic and cavitation tests of pump，it is con— eluded that the pump can work stably in 25％rated flow condition．The analyses of gas parameter, inlet pressure，outlet pressure and efficiency of turbo under varied conditions indicated that the turbo can also work stably．The conclusions made above age verified by engine test．
