Abstract:
An impact attenuation system comprises an aluminum honeycomb sheet having a top surface and a bottom surface. The aluminum honeycomb sheet defines a plurality of approximately hexagonally shaped cells. The bottom surface defines a single sheet of contiguous cells and the top surface defines two or more islands of contiguous cells separated by one or more slits. At least a portion of one or both of the top surface and bottom surface may be covered by a polymer skin. The polymer skin may comprise carbon fibers and/or fiberglass.
Abstract:
A protective suit for protecting personnel from explosive blast detonation and ballistic threats includes a rifle defeating flexible ballistic and fragmentation resistant inner body armor vest with coverage designed to wrap completely around a torso and abdomen of a body. It further includes an outer garment coupled to the inner body armor vest, such as by a quick release system; wherein the outer garment is a unitary garment dimensioned to cover the body from the base of the foot up to the head and outward to the wrists. A collar is attached to the outer garment, wherein the collar comprises a frontal yoke region for providing additional ballistic and fragmentation protection, and a helmet provides additional ballistic and fragmentation protection.
Abstract:
A shovel head counterweight for a helmet has been described. The counterweight has a mass that acts to counterbalance other objects attached to a helmet, such as night vision goggles. The shape and thin profile of the counterweight distributes the mass across the surface of the helmet to decrease strain on the user's neck. In addition, the underside of the counterweight is contoured to snuggly fit against the curvatures of the helmet. The counterweight also has one or more fasteners for removably attaching the counterweight to the helmet. The fastener(s) can also be used to attach a bar for use as a shovel. The counterweight has a digging edge for shoveling and a concave underside for scooping dirt or other material.
Abstract:
Ballistic composite articles comprising a fabric section, an overlay section disposed on the strikeface of the composite article and comprising a thermoplastic resin, and optionally an adhesive layer disposed between the fabric section and the overlay section are described. The ballistic composite articles can provide comparable or improved protection against projectile threats relative to conventional ballistic composites consisting only of a same-type fabric section having comparable areal density, as evidenced by comparable V50 values and/lower backface deformation values when tested under the same conditions.
Abstract:
A helmet cover includes a cover configured to extend over a helmet and at least one mount attached to the cover. In one embodiment, a backing plate is coupled to the at least one mount and the cover is sandwiched between the backing plate and the at least one mount.
Abstract:
A helmet assembly including a mandible bracket configured to connect a mandible to a helmet, at least one strap connected to the mandible bracket and configured to extend from the mandible bracket to a rear portion of a helmet. The assembly includes at least one strap guide having a strap engaging portion connected to the strap along a length of the strap for connecting the strap to a helmet, and a fastener engaging portion configured to connect to a fastener attached to a helmet.
Abstract:
Disclosed herein are engineered composite materials suitable for applications that can benefit from a composite material capable of interacting with or responding to, in a controlled or predetermined manner, changes in its surrounding environment. The composite material is generally comprised of one or more layers whereby each layer is comprised of a plurality of particles having a predetermined median particle size diameter. The predetermined media particle size in each layer, when viewed in cross section, can form a particle size gradient such that the median particle size of each layer sequentially decreases (or increases) across the cross section of the material. Particles can further be core-shell particles releasing their core material upon actuation.
Abstract:
A ballistic armor helmet has two or more shell elements which are fixed to one another to define one or more ventilation gaps. The shell elements preferably overlap to keep projectiles from entering the helmet.
Abstract:
Reactive protective armors for diverting hitting bullets, shrapnel and small shells away from a trooper's helmet, vest and/or away from the skin of vehicles, planes, helicopters or marine vessels are described. The protective armor consists of multiplicity of reactive units, which cover the protected object like tiles. Each reactive unit includes tiny explosives on one side and parallel hinges opposite to the explosives. The hitting armament detonates the explosive, which in turn rotate the plate, thus diverting the bullet away from the protected object. Another embodiment of the reactive- protective unit is a pressurized cell full with noninflammable fluid or gel. In thi case the protected object is covered with multiple pressurized cells. When a bullet or shrapnel punctures the skin of the cell the fluid o gel bursts and pushes the bullet away from the protected object. It is aportant to mention that the bullet activate only one unit, living the other units intact and ready to take other hits.
