| Abstract: | The inducer is a key component of the liquid propellant rocket engine(LPRE),which can effectively raise the suction performance of the main pump.The basic types of LPRE inducer were introduced.The basic concept and design theory were then presented.Furthermore,the design criteria of some important geometry parameters of the high-speed rotational plate inducer were recommended and analyzed.Finally,a high-speed rotational inducer for a LPRE was designed by this method.The CFD results indicated it had a good h... |
