| 摘 要： | 燃烧加热风洞是目前开展超燃冲压发动机地面模拟试验的主要设备。燃烧加热风洞的试验时间（脉冲式和连续式）及燃烧方式（氢-氧燃烧、碳氢-氧燃烧）均会对发动机试验结果产生一定影响。研究了氢-氧燃烧脉冲风洞与氢-氧燃烧连续风洞、酒精-氧气燃烧连续风洞的数据相关性。研究表明:对于同为氢-氧燃烧的脉冲风洞和连续风洞，在相同试验状态下，发动机推进流道压力系数分布规律一致，连续风洞试验的燃烧室压力高于脉冲风洞试验值，连续风洞的发动机推力收益比脉冲风洞高10%左右；对于氢-氧燃烧脉冲风洞和酒精-氧气燃烧连续风洞，发动机推进流道压力系数分布规律一致，连续风洞试验的燃烧室压力高于脉冲风洞试验值，连续风洞的发动机推力收益比脉冲风洞高5%左右。

| Abstract: | The comparison tests of impulse and continuous combustion heated facilities were conducted. For Hydrogen-Oxygen combustion heated impulse and continuous facilities, the pressure coefficient distributions of the engine flow path were coincident but the engine thrust gain in continuous facility was 10% larger than that in the impulse facility. For Hydrogen-Oxygen combustion heated impulse facility and Alcohol-Oxygen combustion heated continuous facility, the pressure coefficient distributions of the engine flow path were coincident but the engine thrust gain in continuous facility was 5% larger than that in the impulse facility. |
