氢燃料超燃冲压发动机因其高比冲特性而成为航空航天飞机发动机的备选方案。为了进一步提高发动机的性能，对氢燃料超燃冲压发动机的燃烧模式转换进行了研究。为了识别超燃冲压发动机和冲压冲压发动机在推进性能和经济性方面的差异，对双模超燃冲压发动机进行了热力学循环分析，为发动机运行模式的选择和优化提供依据。通过对比分析发现，在满足比推力要求方面，冲压模式循环优于超燃模式循环。从性能优化的角度出发，双模超燃冲压发动机的燃烧模式转换应发生在马赫数6-7范围内。因此，当飞行马赫数小于6时，双模超燃冲压发动机应尽可能在冲压模式循环下工作，燃烧模式在飞行马赫数6 - 7范围内由冲压模式循环向超燃模式循环过渡。
Hydrogen fueled scramjet is a candidate for use as the engine of the aerospace plane for its high specific impulse. To further improve the engine performance, analysis of combustion mode transition for a hydrogen fueled scramjet engine was investigated in this study. In order to identify the differences between Scram- and Ram-mode cycles in propulsive and economic performances for selection and optimization of operation modes, a thermodynamic cycle analysis was made with a dual-mode scramjet engine. It was found through comparative analysis that the specific impulse of the Ram-mode cycle was superior to that of the Scram-mode cycle in meeting the specific thrust requirement. From the viewpoint of performance optimization, the combustion mode transition in a dual-mode scramjet engine should occur in the range of Mach number 6–7. It was therefore concluded that a dual-mode scramjet engine should be operated as much at the Ram-mode cycle as possible when the flight Mach number is less than 6, and the combustion mode transition between Ram-mode cycle and Scram-mode cycle should take place in the range of flight Mach number 6–7.
