Technical Memorandum of National Aerospace Laboratory
Two apparatuses were designed and constructed for experimental investigation of RCS (Reaction Control System) jet simulation in the NAL large hypersonic wind tunnel. The first one is a gas supply capable of mixing four kinds of gas and to alter total temperature. Four pressure steps were successfully obtained by changing the angle of attack of the model in 60 second. The second one is a nozzle thrust test stand with a load cell. The measured thrusts were proportional to the jet total pressures owing to the interference free piping design. Compared to the theoretical thrust, total pressure loss through the scaled nozzle was found to be up to 5 percent. The accuracy of the most important jet parameter, pressure ratio, was successfully increased.
