Problems solved by technology

Such an occurrence can, obviously, have very significant detrimental effects on the systems and personnel within a vehicle having its armor defeated in such a manner.
For that reason, and the fact that such weapons are effective, these weapons have proven troublesome to vehicles using conventional armor.
While any anti-armor projectile can be defeated by armor of sufficient strength and thickness, extra armor thickness is heavy and expensive, adds weight to the armored vehicle using it, which, in turn, places greater strain on the vehicle engine and drive train, and thus has a low “mass efficiency.”

second embodiment

[0039]FIGS. 1 and 3 depict a second embodiment, armor subsystem 125, of armor system 10. As best seen in FIG. 3, armor subsystem 125 may include a first element 130, a second element 135, and a plurality of spacing elements 140. First element 130, second element 135, and spacing elements 140 may form a cavity 145 that holds a fill 150. Armor subsystem 125 may also include a mount assembly similar to mount assembly 65 of armor subsystem 25. Spacing elements 140 may be similar to spacing elements 45 of armor subsystem 25, and cavity 145 may be similar to cavity 50 of armor subsystem 25.

[0040]First element 130 may lead second element 135 relative to trajectory 15. First element 130 may include a plurality of layers 155 and an intermediate layer 160 that may be disposed between layers 155. Layers 155 may be sheet-like layers including material such as, for example, glass, transparent ceramics, acrylic, polycarbonate, aluminum, delrin, UHMW PP, UHMW PE, and / or borosilicate. Layers 155 ma...

third embodiment

[0043]FIGS. 1 and 4 depict a third embodiment, armor subsystem 225, of armor system 10. Referring to FIG. 4, armor subsystem 225 may include a layer 230, at least one transparent armor layer 235, at least one seal 240, and at least one frame element 245. Layer 230, transparent armor layer 235, and seal 240 may be supported by frame element 245 and may form a cavity 250 that holds a fill 255.

[0044]Layer 230 may lead transparent armor layers 235 relative to trajectory 15, and layer 230 may be similar to first layer 35 and second layer 40 of armor subsystem 25. To facilitate use in a window of vehicle 11, layer 230 may include a transparent material. Layer 230 may be spaced apart from the at least one transparent armor layer 235.

[0045]The one or more transparent armor layers 235 may include glass, transparent ceramics, acrylic, polycarbonate, and / or borosilicate. Transparent armor layer 235 may be of any suitable thickness such as, for example, between about ⅛″ and about 6″ thick.

fourth embodiment

[0048]FIGS. 1, 5, and 6 depict a fourth embodiment, armor subsystem 325, of armor system 10. Referring to FIGS. 5 and 6, armor subsystem 325 may include a modular array 330, a support system 335 for providing structural support to modular array 330, and a filling system 340 for providing modular array 330 with fill.

[0049]As depicted in FIG. 6, which is a sectional view of FIG. 5, modular array 330 may include a ballistic module 345, a plurality of fill modules 350, and a spall module 355. Ballistic module 345 may provide protection against ballistic threats to vehicle 11, fill modules 350 may provide additional protection against threats to vehicle 11, and spall module 355 may provide protection against spalling of armor system 10. Ballistic module 345, fill modules 350, and spall module 355 may be connected by any suitable technique known in the art such as, for example, by welding or by mechanical fasteners.

[0050]Ballistic module 345 may be a ballistic-resistant layer that leads f...

Abstract

An armor system for protecting a vehicle from a projectile, the projectile having an expected trajectory, is disclosed. The armor system has a material capable of being detonated and configured to substantially retain a shape, wherein the material leads a vehicle exterior surface relative to the expected projectile trajectory. The material has a dimensional thickness that is greater than a minimum detonation thickness of the material.

Description

TECHNICAL FIELD [0001]The present disclosure relates to an armor system that resists penetration by projectiles.BACKGROUND [0002]Conventional armor may be subjected to a variety of projectiles designed to defeat the armor by either penetrating the armor with a solid or jet-like object or by inducing shockwaves in the armor that are reflected in a manner to cause spalling of the armor such that an opening is formed and the penetrator (usually stuck to a portion of the armor) passes through the armor, or an inner layer of the armor spalls and is projected at high velocity without physical penetration of the armor.[0003]Some anti-armor weapons are propelled to the outer surface of the armor, where a shaped charge explodes to form a generally linear “jet” of metal that will penetrate solid armor. Such weapons are often called Hollow Charge (“HC”) weapons. A rocket propelled grenade (“RPG”) is such a weapon. An RPG 7 is a Russian origin weapon that produces a penetrating metal jet, the t...
