Abstract
A warhead casing is designed to protect the high explosive material therein from open fires or other sources of intense heat which might cause premature explosion of the warhead. The warhead casing is relieved throughout the greater part of its outer circumference and may be then counter-relieved over a slightly lesser distance. The relieved area is filled with an ablative material covered by a protective intumescent coating, for example, of fire resistant, impregnated cloth.
Claims6
In a thermal insulation system in combination with a missile skin or the like for the protection of explosive material in the warhead section of the missile from the effects of aerodynamic heating or open fires, the combination comprising:
- a substantially cylindrical web of metal forming a warhead casing;
- said casing being centrally relieved or recessed in steps forming inner and outer areas between steps;
- an inner layer of insulative material filling the inner area next to said metal casing;
- and
- an outer layer of fire resistant material filling said outer area between steps;
- the system being so constructed and arranged that the warhead section as a whole presents an outer surface coincidental in dimensions with the outer skin of the remainder of the missile.
