| 摘 要： | 为了研究二次流温度对推力矢量的影响规律，本文基于二次喷射的基本原理，利用计算流体力学(CFD)软件，对不同温度的二次流进行了模拟仿真分析。结果表明，在相同喷射压强和喷射流量下，二次流温度越高，在扩张段影响的范围就越大，但产生的侧向力和温度并不是简单的正变关系。在此分析的基础上，提出了一种合理利用二次流温度的工程方案。

| Abstract: | In order to study the effect of secondary flow temperature on thrust vector control,based on the principle of secondary injection,the numerical simulation is carried out by using the CFD software for different injection temperatures.The results show that the influencing scope of the secondary injection is larger as the injection temperature is higher.However,the relation between the side thrust and the injection temperature is not simply direct.On the basis the analysis,an engineering project using the seco... |
