Abstract:
In order to obtain the essential dynamic transfer function of the engine pump which is necessary for POGO stability analysis of the new generation large launch vehicle and dynamics research of the liquid rocket engine, a hydraulic test for the dynamic characteristics of a full-scale LOX/kerosene staged combustion cycle engine pump with speed drop-down was conducted, in which normal temperature water is taken as the test medium. The hydraulic test theory, simulation criterion, isolation tank design, exciting system design, control and measurement analysis system design, test details and data analysis method are thoroughly discussed in this paper. The POGO dynamic characteristics parameters and their disciplinarian laws of the oxygen pump were successfully identified through the test, which would be helpful to other hydraulic test and the real medium test.
