AI Technical Summary

Benefits of technology

The present invention provides a reactive armour module that includes a first and second extreme, steel layers, explosive layers, and a trigger screen. The trigger screen is designed to detonate the explosive charges in a timed manner in response to an incoming projectile, creating a scissoring explosive effect. This results in a significant increase in the ability of the armour to protect against projectile-based damage.

Problems solved by technology

The effect is to change the angle of incidence and thus reduce the integrity of the jet.
Commonly, this may involve detonating the reactive armor before the main charge arrives, causing the timing of the counter-explosion to fail to disrupt the main charge which comes with the second detonation stage.
Since the reactive armor is the only element that enables the armored vehicle's integral armor to sustain an impact of a HEAT jet, as the reactive armor was compromised by the first detonating stage, the main charge (second detonation) has an increased likelihood of penetrating the main armor of the vehicle.

Embodiment Construction

[0069]Reactive armour according to the present embodiments comprises an explosive reactive armour module comprising a first triggering screen and an explosive layer; and at least one explosive module placed in proximity to the reactive armour module and connected to said first triggering screen for detonation.

[0070]Irrespective of use of an explosive module, the reactive armour module may have shaped charges to produce a shaped wavefront, and the triggering screen may be divided into at least two triggering parts, each part triggered by a different approach angle of an incoming projectile and each part configured to initiate an explosion in a different part of the reactive armour module or in a different explosive module if provided.

[0071]FIG. 1 illustrates the general structure of a HEAT-shaped charge Tandem warhead 10. Warhead 10 comprises a tip 11, initial (first) charge 12, a first-stage fuse 13, a spacing rod 14, a main charge 15, and a second-stage (main-charge) fuse.

Description

FIELD OF THE INVENTION[0001]The invention relates in general to the field of protecting armored vehicles or structures from approaching Kinetic Energy Penetrators (KEP) or rocket propelled HEAT warheads. More specifically, the invention relates to the protection of armored vehicles or structures from approaching Tandem warheads.BACKGROUND OF THE INVENTION[0002]Essentially HEAT (High Energy Anti-Tank) munitions operate by piercing the exterior armor of armored vehicle's, killing and maiming the crew inside, disabling vital mechanical systems, or both.[0003]In order to enable an armored vehicle to sustain a shaped charge HEAT impact (hereinafter referred as HEAT), an external explosive element titled Explosive Reactive Armor (ERA), is attached to the vehicle's armor.[0004]The standard ERA consists of sheets or a slab of high explosive, sandwiched between two plates, typically metal, called the reactive or the dynamic elements.[0005]In one example, and in order to neutralize an incomin...
