摘　　要：以推力矢量燃气舵为研究对象,采用流固耦合传热数值分析方法,得到了舵偏角分别为0°,5°,10°,15°,20°时燃气舵流场及流固温度场,并将流固耦合传热条件下的流场参数及温度场参数分别与相应的纯气相条件下的参数进行对比,为燃气舵的气动设计、热应力分析,以及隔热防护给出了指导性结论,分析结果很好地符合了试验结果,具有良好的工程应用性。This paper researches the thrust vector internal controller （TVC）. Using fluid-solid cou- pled heat transmission numerical analysis method to get the internal controller flow field and temperature field when the rudder angle is 0°, 5°, 10°, 15° and 20°. Parameters of the flow field and temperature field under fluid-solid interaction heat transmission are compared with those in the condition of pure gas phrase. It supports the constructive conclusions for structure design of TVC, thermal stress analysis and heat insulation protection design. The analysis conclusions correspond with the experimental results, and have excellent project applicability.
