Abstract
A thermal insulation jacket for a gun barrel, especially a cannon barrel, where the thermal insulation jacket includes a metal jacket that surrounds the gun barrel. In order to prevent uneven heating of the surface of the gun barrel within the thermal insulation jacket, an additional area that is especially effective at reflecting thermal radiation is provided on the inner surface of the metal jacket that lies opposite the underside of the gun barrel, so that when the gun barrel heats, the temperature differences between the upper side and the underside of the gun barrel are at least partially compensated. For this purpose, a reflective film is provided as the area that is a good reflector of thermal radiation. This reflective film is adhesively attached to the metal jacket.
