当物体以高超声速飞行时,其头部会产生一道非常强烈的弓形激波,激波后的温度非常高,计算激波后的温度,对于再入飞行器表面的热防护有着重要的意义。本文通过数值模拟分析可以看出,等离子体环境将对飞行器产生非常大的影响,例如黑障现象,此外还会干扰飞行器内电子设备的运行,对再入飞行器的壁面产生冲击,甚至烧毁。因此,计算激波后的温度,对于再入飞行器表面的热防护有着重要的意义。
When an object is flying at hypersonic velocity, a very strong bow shock is generated at the head of the object. The temperature after the shock wave is very high. Calculation of the temperature after the shock wave is of great significance for the thermal protection of the reentry vehicle surface. Through numerical simulation, we can see that the plasma environment will have a very big impact on the aircraft, such as the black barrier phenomenon, in addition to interfering with the operation of the electronic equipment in the aircraft, impacting the wall of the reentry vehicle and even burning down. Therefore, calculating the temperature of the shock wave is of great significance for the thermal protection of the reentry vehicle surface.
