Abstract:

An ordnance item casing construction which enables case venting and controlled combustion of high energy fuel contained within the casing when the ordnance item is exposed to a high temperature environment. This casing construction utilizes a perforated thermally insulating composite doubler and series of thermally conductive plugs aligned with cavities in the casing wall, and applied to the exterior of the ordnance item. Heat from the high temperature environment is conducted by the plugs to the casing wall. Local ignition and combustion of high energy fuel within the casing rapidly burns through the wall at regions of reduced wall thickness caused by presence of the cavities. The interior of the casing is thereby vented, and catastrophic pressure buildup within the casing is prevented. Author
