Technical Memorandum of National Aerospace Laboratory
A gas supply device was constructed to supply the reaction control nozzle of the Japanese space shuttle model, HOPE (H-2 Orbiting Plane), with nitrogen gas at an arbitrary pressure. The variation of the supplied gas pressure is controlled up to 5 MPa manually or electrically by imposing a control voltage. The variation of the instantaneous temperature, the pressure and the flow rate of the supplied gas are recorded to evaluate the control performance of the device. The supplied gas pressure is controlled to a constant value within one second, while the temperature varied greatly over five seconds. To measure the thrust of the reaction gas jet a test stand without interaction by the supplied high pressure gas through the piping was devised. The thrust of supersonic jet nozzles for jet Mach number 2.5, 3.0, 3.5 and 4.0 showed almost the same values as theoretically predicted.
