| Abstract: | A new method for the exhaust nozzle of the hypersonic ramjet in ground tests has been developed in this paper.The high enthalpy gas was produced steadily in double detonation driven shock tube to simulate the condition of the ramjet at high Mach number.And a new method to calculate the thrust with pilot pipe was given according to the law of conservation of momentum.All these provided foundation for catalysis compound experiment. |

| Keywords: | detonation air-breathing propulsion conservation of momentum thrust measurement |
