Abstract
An existing booster and fuze combination is modified to provide relief from emperature and pressure buildup in an open fire environment. The booster explosive, thus, is encased in a low temperature melting plastic and the main housing is vented by boring a number of passages through the major thread diameter shoulder of the fuze case.
Claims2
In a booster-fuze combination wherein a booster and fuze are fastened together as a unit and inserted in a housing contained within a warhead, the improvement comprising:
- said fuze being contained within a metal container having a threaded shoulder for attachment within a threaded housing and a lesser diameter threaded end portion receiving a booster cup;
- an explosive booster material in said cup having a predetermined self-detonation temperature;
- said booster cup being manufactured of a material which will soften and melt before the self-detonation temperature of the booster;
- and
- a plurality of through holes bored longitudinally through said fuze container shoulder.
In a booster-fuze combination wherein a booster and fuze are fastened together as a unit and inserted in a housing fastened within the rear bulkhead of a warhead, the improvement comprising:
- said fuze being contained within a metal container having a threaded end portion receiving a booster cup;
- an explosive booster material in said cup having a predetermined self-detonation temperature;
- said booster cup being manufactured of a material which will soften and melt before the self-detonation temperature of the booster;
- said booster cup being spaced from said metal container to provide an expansion chamber;
- and
- venting means rearward of said bulkhead.
