Abstract
The precursor-follow through kinetic energy explosively formed penetrator assembly greatly enhances target penetration. It is formed of two sections: an initial precursor penetrator followed by a penetrator encapsulating a reactive material. The target will initially be perforated by the precursor penetrator with the second follow through penetrator containing a reactive material causing internal damage through a secondary reaction.
Claims7
A kinetic energy, explosively formed penetrator assembly, comprising:
- a housing having an inner surface;
- an explosive billet disposed within the housing;
- a liner disposed against the explosive billet within the housing;
- a reactive material disposed within the liner;
- wherein the liner is generally concave shaped and includes a peripheral rim;
- wherein the peripheral rim of the liner abuts against the inner surface of the housing;
- and
- wherein when the liner is expelled from the housing, the peripheral rim of the liner folds forward, causing the liner to envelop the reactive material to form a two-stage penetrator.
