ORDNANCE DEVICE WITH EXPLOSION PROTECTION

Abstract

Controlled venting of combustion gases from an explosive material encased in a shell, as used in ordnance constructions such as rocket motors, warheads and bombs, is achieved by affixing a composite solid mass to the shell casing at a preselected location presenting low risk of damage to surrounding equipment or personnel. The solid mass is in two portions, the first being an ignition mix (in direct contact with the shell) which ignites at a temperature of 400° F. to 600° F. to react exothermally. The second is a reaction mix ignitable by the energy released by the ignition mix to itself release sufficient energy to degrade the metallurgical structure of the case. With the case thus weakened at a localized point, the case will rupture preferentially at that point upon an interior pressure buildup, and explosion of the entire case can be avoided.
