| 摘 要： | 经分析,某运载火箭定向姿控发动机所在环境的主要热源为游机喷管辐射、游机燃气羽流辐射、涡轮废气管辐射等。计算得出各受热危险部位所接受的辐射热流,依据热流值提出了对辐射热流较大的地方采取隔热材料包覆的热防护方案,并对热防护方案进行数值仿真和试验验证,试验值与仿真结果接近。

| Abstract: | The main thermal sources of the attitude correction and control liquid rocket engine of the X type launch vehicle were analyzed. The thermal sources are nozzle wall radiation, combustion gas radiation, gas turbine wall radiation, etc. The heat flux values of each key positions were obtained by numerical calculation. The thermal protection scheme was put forward. This scheme was demonstrated by numerical analysis and experiment, and the test values fit well with the numerical analysis results. |
