热障 X-2飞机的试飞除证实惯性耦合现象外也得出很多“气动加热”的数据。当它的速度达到2.5马赫,机头的油漆就开始出现过热剥蚀现象。物体在大气中运动会受到空气冲击和磨擦产生高温是早已预料到的。理论上物体表面产生的驻点温度(即空气直接撞击物体表面,相对速度为0的那一点位置的温度)与飞行马赫数有关,也与当时大气温度有关。例如2.0马赫时驻点温度
Tensile X-2 aircraft test flight in addition to confirming the phenomenon of inertial coupling also gave a lot of “pneumatic heating” data. When its speed reached Mach 2.5, the head of the paint began to appear overheating phenomenon. It has long been expected that objects that move in the atmosphere will be subjected to air shocks and friction to produce heat. Theoretically, the stagnation temperature (ie, the temperature at which the air collides with the surface of the object directly at a point where the relative velocity is zero) produced by the surface of the object is related to the flight Mach number and also to the then atmospheric temperature. For example Mach 2.0 station temperature
