Abstract: In one aspect, the present disclosure is directed to a blast-resistant armored land vehicle. Wheels or tracks may be attached to the vehicle by an independent suspension. The vehicle may include a body comprised of sheet materials, the body having a longitudinal centerline, an upper portion including opposite side portions, a first bottom portion defining a V, with the apex of the V substantially parallel to the longitudinal centerline of the vehicle and extending along a portion of the vehicle, and a second bottom portion defining a V, with the apex of the V substantially parallel to the longitudinal centerline of the vehicle and extending along another portion of the vehicle. The first bottom portion further includes an energy-absorbing member extending longitudinally within an interior of the first bottom portion. The energy-absorbing member may be on the inside of the apex of the V and be held in position during the blast by its own inertia.

Abstract: In one aspect, the present disclosure is directed to a system for protecting a vehicle from a mine. Upon detonation the mine may yield ejecta having an expected trajectory. The system has a first layer of material disposed outside of an underbody of a hull of the vehicle. The first layer includes a base disposed in a direction substantially parallel to the underbody and a protrusion that narrows as it extends away from the base in a direction opposing the expected ejecta trajectory. The system also has a second layer including a material having a shock wave transmission velocity that is higher than a shock wave transmission velocity of the material of the first layer. The system further has an exterior layer substantially covering the first and second layers, and the exterior layer has an exterior surface that faces away from the underbody and toward the expected ejecta trajectory.

Abstract: An armor system for defeating rocket propelled grenade-type missiles and/or high velocity jets created by shaped charges directed at a vehicle includes a grid layer such as a net and/or an array of slats or bars (“RPG”) spaced from an outer surface of the vehicle by support members. The grid layer has a characteristic mesh size or bar/slat spacing to disrupt the missile firing mechanism. The system also has a shaped layer having a plurality of tapered members formed from a fiber-reinforced material, the tapered members positioned between the grid layer and the vehicle outer surface and having respective apex ends proximate the distant the grid layer and base ends, the tapered members defining with adjacent tapered members a plurality of depressions opening in a direction to receive an incoming conical portion of an unexploded RPG-type missile, or a jet emanating from an exploded RPG or other anti-armor device, and a layer of fiber-reinforced material abutting the base ends of the tapered members.

Abstract: A armor system for protecting a vehicle from a projectile, the projectile having an expected trajectory and the vehicle having a hull, is disclosed. The armor system has a modular armor subsystem configured to be mounted exterior to the vehicle hull. The modular armor subsystem has a leading layer having metal, leading relative to the expected projectile trajectory, and an intermediate sheet-like layer having low density material, of a density less than metal, abutting a rear surface of the leading layer. The armor system also has an intermediate sheet-like layer having glass fiber material and abutting a rear surface of the intermediate low density material layer, and an intermediate sheet-like layer having metal and abutting a rear surface of the intermediate glass fiber layer.
