| 摘 要： | 提出了利用亚音速高温燃气流进行近空间高超飞行器热环境地面模拟的试验方案,在试验装置试验段,通过高温高速的燃气流引射低速的冷气流,达到仅使飞行器头锥驻点附近区域产生局部高温而其余头锥蒙皮表面低温的目的.对某型高超音速飞行器的头锥利用高温燃气进行加热并利用CFD(Computational Fluid Dynamics)方法对13种模拟工况进行了数值仿真分析.将数值模拟计算结果与飞行器在高超音速飞行状态下对应机体部位气动热的理论计算值进行了对比,证实了亚声速高温燃气热环境模拟方法的可行性,为高温燃气地面模拟设备技术方案论证提供了依据.

| Abstract: | An experimental method using subsonic high-temperature gas flow to simulate aerodynamic thermal environment of near space hypersonic vehicle was introduced.In the test section of the experiment equipment,the room temperatwe air was ejected by the subsonic high-temperature gas flow to make the heat distribution of the experimental condition in line with that of the real flight condition on the cap.13 experimental conditions were analyzed using computational fluid dynamics(CFD).The numerical analysis verifies... |
