针对超燃冲压发动机(Scramjet)向更高马赫数拓展遇到的技术挑战,提出了磁流体-斜爆震冲压发动机(MODR)(Magnetohydrodynamics-Oblique Detonation Ramjet,Abbr MODR)概念,通过其热力学过程与传统冲压发动机、磁流体(Magnetohydrodynamics,Abbr MHD)能量旁路冲压发动机进行对比分析,获得MODR热力循环优势以及工程实现需要解决的关键技术。MODR对拓展高超声速推进工作范围,提高动力装置性能具有重要意义。 

Some technology challenges have been encountered for extending scramjet operation envelope to higher flight Mach number. A new conceptual Ramjet of Magnetohydrodynamics-Oblique Detonation Ramjet(MODR)was proposed.Compared with the thermodynamic cycle efficiency of classic ramjet and ramjet with MHD bypass,MODR has more competitive advantages. The key technologies for MODR were presented, which need to be resolved in future research. MODR may expand hypersonic propulsion operation range and improve the performance of hypersonic propulsion system. Thus,it is important to take further exploration for MODR. 
