Abstract: | In this paper,a small flow rate hydrocarbon turbine pump was used to pressurize the fuel supply system of scramjet engine.Some experiments were carried out to investigate the characteristics of turbine pump driven by nitrogen or combustion gas under different operating conditions.A experimental database with regard to the curves of the rotational speed,mass flow rate and net head with regard to centrifugal pump were plotted.These curves were represented as functions of the pressure and temperature at turbine inlet/outlet and the throttle diameter at downstream of centrifugal pump.A sensitivity study has been carried out based on design of experiments.The experimental was employed to analyze net head of centrifugal and throttle characteristics.The research results can accumulate foundations for the close loop control system of turbine pump. |
