The cost and weight of these various armoring materials and techniques are generally factors for designers. Additionally, historical armor materials and techniques generally require continuous updating to meet the demands of modem armaments. For instance, while steel has been used in traditional armor applications, it is generally impractical to employ steel in the dimensions needed to completely protect against all projectiles, as any vehicle carrying such armor would be severely hampered due to the excessive weight.

Armor and shielding that is undersized or under-strengthened for its purpose is largely useless. In some cases, this scenario may give a false sense of security to the user.

Armor generally must be designed to protect against a wide variety of threats. The angle of attack, the method of threat, munitions used, and the frequency of danger are all factors that designers may consider.

While some armor is able to withstand the force and penetration of a single strike in a particular region, multiple strikes in the same zone generally represent an unprotected threat. Some armors employ explosive charges and "smart armor" techniques that engage an anticipated projectile, however these techniques severely limit the multiple strike capabilities in the same zone.

Accordingly, there exists a need to address these and other deficiencies associated with conventional armor techniques. US 5,, discloses a flexible protective armour which includes an outward layer of hard geometric shapes, preferably spheres, which are firmly mounted to an outward side of a flexible membrane. The flexible membrane is a ballistic fabric which is formed of a sixty degree weave of ballistic fibres.

The spheres have mounting portions and side engagement portions. The mounting portions of the spheres are firmly bonded to the flexible membrane by a rigid adhesive, with the spheres tightly packed to mechanically interlock the side engagement portions of adjacent ones of the spheres for rotating relative to on another, free of the rigid adhesive.

The kinetic energy of a fast moving projectile is absorbed upon impact with the flexible protective armour by curving of the layer of spheres and the flexible membrane, tensioning the ballistic fibres of the flexible membrane within the elastic range of the ballistic fibres so that the flexible protective armour will rebound after impact.

A fibre-reinforced pliable material is disposed within the interstitial spaces between the spheres and the flexible membrane to absorb the energy of the spheres when the flexible protective armour is rebounding after impact.

A flexible, impact resistant polyurethane coating extends across an outward side of the layer of spheres. EP 0 discloses a dynamic armor system according to the preamble of claim 1 and a method of dynamic armoring according to the preamble of claim 4.

It shows a structure which comprises a panel including an elastically deformable laminate matrix, which supports a plurality of rigid elements located in the front part of said panel, said elements constituting means for absorbing the energy of the incident projectiles and for unstabilizing them in response to the impact of said projectiles on said elements and the elastic deformation of said matrix.

Each of the tiles has an outer, front surface designed that, upon impact by a ballistic projectile, deflects the projectile from its initial path. Subsequent tiers of the barrier are comprised of layers of a flexible material interspersed with layers of a ballistic liquid or at least one layer of ballistic fibre.

When tiles are impacted by a projectile, the impacted tile is pushed into the laminate layers of the barrier, thereby substantially multiplying the area of the barrier that resists the impact force of the projectile as the projectile enters the barrier. The invention provides a system and method as claimed hereinafter. Elements in the figures, drawings, images, etc. For example, the dimensions of some of the elements in the figures may be exaggerated relative to other elements to help improve understanding of various embodiments of the present invention.

Furthermore, the terms 'first', 'second', and the like, are used for distinguishing between similar elements and not necessarily for describing a sequential or chronological order. The following description is intended to provide convenient illustrations for implementing various embodiments of the invention. Furthermore, such armor may comprise various forms, layers, sizes, thicknesses, textures and dimensions. The armor may be adapted as a generic protective external surface.

Referring to Figure 1 , a system for dynamic armor generally comprises a first surface layer , an absorbing filler layer and a force absorbing material e. These layers may be integrated into unitary material or may comprise a plurality of divisional layers. Additionally, these layers may be assembled in various orders with or without duplication between layering.

First surface layer may comprise the external surface of dynamic armor This surface may be the face of the absorbing filler layer or it may comprise a layer of additional material.

As the process is completed at the speed of electricity the plates are moving when struck by the projectile causing the projectile energy to be deflected whilst the energy is also dissipated in parting the magnetically attracted plates. For analyzing reactive plate velocities, the Gurney equations are commonly used. Military Wiki Explore. Popular pages. Raaen, Jr. Project maintenance.
