EFFECT OF CAVITATION IN PUMP OF TPU ON PARAMETERS OF LRE OPERATION
A computational and experimental study of effect of cavitation in oxidizer pump on TPU parameters of RD180 engine type was carried out. Pressure, flowrate and efficiency characteristics of pump at low values of input pressure, including break-down area of characteristics, are used. A significant effect of development of cavitation in oxidizer pump on engine parameters, in particular the increase in speed of turbopump, turbine power and preburner temperature, is shown. It is planned to introduce the characteristics of pumps of TPU and booster pumps with cavitation into mathematical model of engine in next phases of development of this topic.
