这份报纸由在与氢的马赫数字 6 的超声的溪流反对喷气论述超音速冲压式喷气发动机神气的热保护的数字调查用 CFD 的造成的超音速冲压式喷气发动机神气模型软件。模拟结果显示当燃料的小数量从神气的鼻子被注射时，鞠躬吃惊从神气被推开，并且热流动在神气被减少，特别在前缘。反对喷气在嘴附近形成一个再通行区域以便神气被低温度盖住燃料并且与免费溪流分开了。适当全部的压力比率能被用来减少不仅空气动力学的加热而且神气的 drag。超音速冲压式喷气发动机的热保护由反对喷气炫耀，这因此被结束是在高热含量保护超音速冲压式喷气发动机神气的有希望的方法之一溪流。

英文摘要：

This paper presents the numerical investigation of thermal protection of scramjet strut by opposing jet in supersonic stream of Mach number 6 with a hydrogen fueled scramjet strut model using CFD software. Simulation results indicate that when a small amount of fuel is injected from the nose of the strut, the bow shock is pushed away from the strut, and the heat flux is reduced in the strut, especially at the leading edge. Opposing jet forms a recirculation region near the nozzle so that the strut is covered with low temperature fuel and separated from free stream. An appropriate total pressure ratio can be used to reduce not only aerodynamic heating but also the drag of strut. It is therefore concluded that thermal protection of scramjet strut by opposing jet is one of the promising ways to protect scramjet strut in high enthalpy stream.
