利用地面风洞测热试验、数值仿真方法和工程计算三种方法,基于突起物局部和大面积无干扰区的热流密度的比值系数(干扰因子),进行了全飞行弹道的电缆罩等局部细小复杂外形的突起物气动热环境预测。该方法能有效克服地面测热实验状态不真实、局部细小结构不能布置测点、数值仿真对网格和湍流模型依赖程度高、复杂突起物热环境无工程算法等问题。
Abstract：Hypersonic aerodynamic heating of local protuberance is investigated with wind tunnel test,numerical simulation and engineering method respectively.According to the radio of thermal environment of local protuberance to body of the missile(interference factor) based on the results of computational and experimental study,engineering method is used to forecast the thermal environment of the cable-protrusions of missile along ballistic trajectory.The method overcome the weakness of heat flux testing because of local fine structure and test condition,numerical simulation that depends strongly on mesh and turbulence models and engineering method with narrow scope of application.
