Temperature of armour

The temperature of armour is the mean value of the temperatures of the first and second armour layer. Because the resistances of the armour layers are calculated based on the temperatures of the corresponding layers, this temperature is not used.

With crossing heat sources, a temperature rise of $\Delta\theta_{0x}$ applies at the hottest point.
