Benefits of technology

[0005]Some embodiments of the disclosure may provide numerous technical advantages. For example, one embodiment of the protective armor system may provide enhanced resistance by adding mass to the penetrator. This added mass may decrease the energy of the penetrator, causing it to be less effective. Further technical advantages of particular embodiments of the present disclosure may include an armor system that is lighter weight than conventional armor. This lightweight armor system may be capable of protecting against a similar threat as a heavier conventional armor system.

Problems solved by technology

This added mass may decrease the energy of the penetrator, causing it to be less effective.

Embodiment Construction

[0011]Shaped charges, in particular explosively formed penetrators (EFPs), also referred to as explosively formed projectiles, may be a serious threat to equipment and personnel on the battlefield. Explosively formed penetrators may have the ability to pierce through the armor of a vehicle and injure or kill the occupants inside. When the armor is pierced by the explosively formed penetrator, spall may result. Spall refers to the fragments of armor that break off of the explosively formed penetrator and / or vehicle and accelerate into the interior of the vehicle. This material may be relatively hot and may move at a relatively high velocity. Thus, spall may be extremely dangerous or deadly to personnel and damaging to equipment.

[0012]FIGS. 1A through 1C show several progressive stages of a shaped charge 10 during explosion. Shaped charge 10 includes a container 12 having an opening 14 with a high explosive (HE) region 16 and a metal liner 18 configured inside. High explosive region 1...

Abstract

In one embodiment, a protective armor system includes first and second armor layers separated by a gap. The second armor layer has a hardness that is less the first armor layer. The protective shield is configured to disperse energy of a shaped charge, such as the energy within a penetrator generated by an explosively formed penetrator (EFP).

Description

RELATED APPLICATIONS[0001]This application claims priority to U.S. Provisional patent application Ser. No. 60 / 983,481, entitled “PROTECTIVE SHIELD FOR A MILITARY VEHICLE,” which was filed on Oct. 29, 2007, and U.S. Provisional patent application Ser. No. 61 / 049,688, entitled “SYSTEMS AND METHOD FOR MITIGATING EXPLOSIVELY FORMED PENETRATORS,” which was filed on May 1, 2008.TECHNICAL FIELD OF THE DISCLOSURE[0002]This disclosure generally relates to protective armor, and more particularly to a protective shield for resisting impacts from shaped charges, such as explosively formed penetrators.BACKGROUND OF THE DISCLOSURE[0003]An explosively formed projectile (EFP) is a type of shaped charge designed to penetrate armor. Penetration of the armor may cause behind armor effects, such as spall. Spall is the armor fragments that break away from the armor of a vehicle as a result of penetration by an explosively formed projectile. These armor fragments may be extremely hot and may be accelerat...
