摘要
阐述冲压发动机尾喷管地面模拟实验的新方法。采用双爆轰技术产生稳定的高焓燃气模拟高马赫数飞行条件下冲压发动机的燃烧气体;利用皮托管测量尾喷管推力,并对测量误差进行了分析;为研究催化复合效应增大推力提供实验基础。
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.
