体-翼干扰区热环境特性分析及预测

高速飞行器的体—翼干扰区热流精确预测对于飞行器生存能力与战术性能的提高具有重要的 意义，是高性能飞行器设计水平的一个重要标志。由于体—翼干扰区流场的复杂性，目前尚 无满足工程设计要求的热环境预测方法，在分析体—翼流场特性的基础上应用文献［1 ］的压力—热流关系式，提出体—翼干扰区的热流预测方法，即压力由N-S数值解给出，热 流应用压力—热流关系式得到，炮风洞的实验结果验证了本文预测方法的可 靠性 。

The Analysis and Calculation of Thermal Environment on the Body-wing Interaction Region

It is significant that accurate forecast of heat flux on the body-wing interaction region of high speed vehicle, which will improve its viability and capabilities of fighting, indicate the ability of high-powered vehicle design.There is no effective fore-cast method of thermal environment presently because of the complexity of flow field at the body-wing interaction region. On the basis of the analysis about characteristic of the flow field at body-wing interaction region, the pressure-heat flux relation formula from referenced1] ,a new forecast method of heat flux was introduced, that is, the pressure were solved by N-S numerical method and the heat flux was presented by pressure-heat flux relation formula. The resuhs of experiment done in the gun tunnel can vali-date the reliability of the forecast method introduced by this paper.
