Abstract
A method of providing a defense against a shaped charge. An outer and an inner armor layer are provided with a medial space between these outer and inner armor layers. One or more defensive shaped charges are positioned in the medial space. If the outer armor layer is attacked by ordnance having an offensive shaped charge, one or more of the defensive shaped charges positioned in the medial space is detonated so as to degrade the effectiveness of the offensive shaped charge and prevent penetration of the inner armor layer.
Claims8
A method of providing a defense against a shaped charge comprising:
- providing an outer and an inner armor layer with a medial space between said outer and inner armor layers;
- positioning one or more defensive shaped charges in the medial space, and if the outer armor layer is attacked by ordnance having an offensive shaped charge;
- generating an electrical current produced when a material selected from the group consisting of a piezoelectric material, an electrostrictive material or magnetostrictive material in the outer armor layer is by the article of ordnance;
- and,
- activating a detonator, in response to the electrical current generated by either the magnetostrictive material, piezoelectric material, or electrostrictive material, which detonate one or more of the defensive shaped in the medial space so as to degrade the effectiveness of the offensive shaped charge.
