ABSTRACT
The part marked with “1” in Figure 1 is a false cap of fuze located at the head of a projectile. When a projectile is travelling at supersonic speed, the false cap is heated (Zhang & Pan 2003.), which causes its temperature to rise, thus forming a steady-state temperature field at last. The temperature of the false cap’s stagnation point is the highest anytime, and the further the distance is between the stagnation point and the point else on false cap, the lower the temperature is. The inner surface and outer surface of the false cap both radiate energy outward, which is called thermal radiation.
