| 摘要: |
| 为进行超燃冲压发动机试验，设计了空气加热器，对其内部流场进行了仿真并与热试车结果进行了比较验证；计算结果表明，所设计的加热器在结构方案
和总体性能方面基本满足设计要求，喷注器喷入的空气降低了冷却面板的温度，燃烧室轴向入口空气能有效保护燃烧室内壁，仿真结果对于加热器的改进设计也起到一定的指导作用。 |

| Abstract: |
| An air-heater was designed for scramjet ground test. The internal flow field in the air-heater was investigated and the results were compared with the test data. The results show that the air-heater basically corresponds with the structure project and performance, the temperature of faceplate is reduced as a result of the air flow from injector-inlet, and the inner surface of the combustion chamber is protected by air flow from chamber-inlet. The results will be helpful for the optimization of the air-heater design. |
