After the long and strenuous eforts covering more than 50 years and the tortuous experiences, feasibility of the scramjet concept has finally been proven. In this paper, the main factors influencing the technical maturity of the scramjet engine are briefly analysed. A matter of utmost concern for this new type of air-breathing engine is the net thrust. The production of engine thrust using supersonic combustion encountered a number of practical requirements which were often found to contradict each other. S...

1引言1.1超声速燃烧与高超声速推进超音速燃烧是一种燃料在超声速气流中混合与燃烧的物理化学过程,这种概念源自超声速燃烧冲压发动机(简称超燃冲压发动机),由美籍意大利空气动力学家安东尼奥·费里在1950年代提出(Ferri et al.1962,Weber et al.1958).这种发动机的特点是几何?
