| 摘 要： | 本文针对以凹腔支板一体化燃烧室为基本结构的超燃冲压模型发动机在自由射流风洞中的性能,主要研究了燃料在不同位置喷入时,燃烧室几何结构/气动性能/燃料混合及燃烧特性的相互耦合,以及对发动机推力性能的影响.结果表明支板与凹腔的一体化在合理配置燃料分布情况下可以获得较好的发动机性能.

| Abstract: | The experimental investigation has been carried out to study the performance of the scramjet model with cavity/strut configuration in the free-jet wind tunnel.The effect on the perfor- mance of the engine model has been researched under the different fuel injections,which related with the configuration,gas dynamics,mixing and combustion in the combustor.The results show that the better performance can be obtained under the matched fuel injection and the cavity/strut structure. |
