Abstract

An auxiliary booster is used to relay and amplify the detonation wave from a standard configured bomb. An explosive system is placed in an extended fuse well to interface with the main charge. The auxiliary booster is initiated as a second, sequential event by this conventional booster charge. Energy of the conventional booster is transmitted into the auxiliary booster charge and the combined energy of the two charges is focused on the auxiliary charge's tapered metal liner. This tapered metal liner is driven through an air gap into the end of the fuse well at hypervelocity. The design of the device provides controlled packaging of energy for the generation of vaporific effects resulting in the collision of the metal liner of the auxiliary charge with the metallic end of the fuse well for enhanced detonation of the main charge.

Claims6

Dependent claims

A detonation system, comprising:

a housing having a fuse well which has a front end and back end, and in which said front end of said fuse well is constructed of materials selected from a group containing cerium aluminum alloys and zirconium;
a main charge which is housed in said housing adjacent to said fuse well;
a booster charge which is housed in the back end of said fuse well, said booster charge being capable of detonation when ignited to produce a detonation wave;
a means for igniting said booster charge;
an auxiliary booster charge which is housed in said fuse well adjacent to said booster charge, said auxiliary booster charge being sequentially detonated by the detonation of said booster charge to ignite said main charge and initiate its detonation;
and
a flyer plate which is fixed in said fuse well between its front end and said auxiliary booster charge, said flyer plate being accelerated by the detonation of said auxiliary booster charge so that it strikes said front end with a high velocity and generates thereby vaporific effects which entail jets of very hot metal particles that enhance the detonation of the main charge, and wherein said flyer plate comprises a tapered metal liner which is fixed in said fuse well to said booster charge, said tapered metal liner being constructed of materials selected from a group containing cerium aluminum alloys and zirconium, said group having known pyrophoric characteristics which enhance the detonation of said main charge.
