超声速掺混与燃烧强化是超燃冲压发动机研制成功的关键技术。本文通过燃烧试验研究了几种超混合器（斜坡）喷射器。特别是，我们在本文中集中在这些注射器斜坡应用“扫掠”的效果。实验结果表明，当流向涡产生较强时，后掠对推力性能影响不大。当流向涡引入不足时，后掠式喷嘴比非后掠式喷嘴具有更好的推力性能。
Supersonic mixing and combustion enhancement is the key technology for success of the development of the scramjet engine. In this study, some types of hypermixer (ramp) injectors were investigated by the combustion test. Especially, we have focused on the effect of applying ‘swept’ to these injector ramps in this paper. According to the experimental result, there was little difference on the thrust performance due to the application of swept when streamwise vortices was strongly generated. When streamwise vortices were not introduced enough, swept type injectors were better thrust performance than unswept type.
