Vertical explosive reactive armor, their construction and method of operation

Abstract

A vertical explosive reactive armor (VERA) comprises the following components: an explosive material (1), an inert plate (2), a damping material (3), a casing (4); a casing cover (5) and a casing upper limiter (6). The VERA additionally could have an expandable material and an uneven surface inert plate. The essential component of the VERA is the casing upper limiter, the purpose of which is to hold back the part of the inert plate after the detonation, which makes the inert plate to bend at an angle. Bent back inert plate is breaking kinetic penetrator by its plane into individual elements and affects the trajectory of the kinetic penetrator. If the penetrator is explosively formed penetrator, the inert plate shatters or partially destroys the integrity of the current of the penetrator by its own plane. Such VERA construction protects against kinetic penetrators, explosively formed penetrators and tandem explosively formed penetrators. These VERA are efficient, compact, easy to manufacture and operate.

Description

technical field [0001] The present invention relates generally to the field of explosive reactive armor. This particular disclosure describes vertical explosive reactive armor, its construction and methods of operation. Background technique [0002] Military vehicles often have armor to withstand the impact of armor piercing projectiles such as shrapnel, bullets or missiles. There are two main types of AP projectiles: kinetic energy penetrator (KEP) and explosively formed penetrator (EFP). Tandem EFPs are often used today, consisting of two priming cartridges: the first cartridge interferes with explosive reactive armor, while the second cartridge damages military vehicles. Military vehicles use explosive reactive armor (ERA) mounted on military vehicles for protection against KEP and EFP. This type of ERA will effectively protect military vehicles from KEP and EFP of different calibers. There are patents describing the structure and method of operation of ERA, however t...

AI Technical Summary

Problems solved by technology

Second, such ERAs are ineffective against tandem AP shells

However, there is a similar problem as in the previous invention: in the case when the container is fastened obliquely to a vertical orientation or retracted from a military vehicle, which is an increase in size and weight to the military vehicle, the ERA takes up a lot of space

However, the problem remained unsolved: it was impossible to simultaneously increase the number of panels and explosive or expandable material layers without increasing the size and weight of military vehicles

Also, ERA is less effective against kinetic AP rounds
