Description
- The present application claims the benefit of U.S. Provisional Application No. 61/642,115 entitled “Buoyant Armor Applique System”, filed May 3, 2012, which is incorporated herein by reference in its entirety.
- The present invention is directed to an armor appliqué system affixable to the exterior hull of an armored vehicle for supplementing the integrated armor of the vehicle. Specifically, the present invention is directed to a modular armor appliqué system having a plurality of interchangeable armored modules with integrated buoyancy elements for offsetting the additional armor weight.
- Armored vehicles are often fitted with additional ballistic armor or blast armor attached to the armored hull of the vehicle to counter specific threats. Specifically, armor appliqués are often fixed to the exterior of the hull to provide an additional armor layer supplementing the integrated vehicle armor. In particular, the increased use of asymmetric improvised explosive devices (IEDs) has required retrofitting of otherwise adequately armored vehicles with additional armor especially along the sides and undercarriage of the vehicle. While attaching additional armor improves the survivability of the armored vehicle against IED threats, the additional armor also increases the weight of the vehicle. The additional weight can affect the overall performance of the vehicle. In particular, the additional weight can significantly impact the swimming ability and cargo capacity of amphibious vehicles.
- Armored amphibious vehicles are commonly tasked as armored personnel carriers capable of transporting personnel and equipment from ship to shore or across bodies of water in addition to across dry land. Unlike purely land or water vehicles, the weight of the vehicle must be taken into consideration for both water and land operation. Moreover, changes in vehicle weight may unequally affect the performance of the vehicle on land and in the water. The increased vehicle weight from armor appliqués can minimally affect the operation of the vehicle on land. However, the same weight increase can significantly compromise the ability of the vehicle to safely travel through the water. Accordingly, the additional armor weight is typically offset by reducing the maximum cargo capacity of the vehicle. The tradeoff between increased protection and reduced cargo capacity creates a need for improving the protection of the vehicle while minimizing the effect on the aquatic performance of the vehicle.
- The present invention is directed to an armor appliqué system for supplementing the integrated armor of an amphibious vehicle without increasing the effective weight of the vehicle in water. The system can comprise a plurality of armored modules individually affixed to the hull of an amphibious vehicle. Each module can comprise a passive or active armor element and a buoyant element sized to offset at least the weight of the armor element when the module is submerged in water.

The individually affixed modules can be arranged end-to-end on the hull of the vehicle to align the armor elements of neighboring modules and create a nearly continuous armor layer over a layer of buoyant elements and the hull. The modules can be provided in a plurality of different shapes and sizes such that the armor layer can be customized approximate to shape and size of the portion of the hull to prove protected. The modules can also be arranged on the hull to provide an armor layer having a shape and size independent of the contours of the underlying hull portion.
- An armored module, according to an embodiment of the present invention, can comprise an armor element, a buoyant element and a module casing having at least one engagement feature for securing the module to a hull of a vehicle. The armor and buoyant elements can be arranged within the module casing such that the buoyant element is positioned between the armor element and the hull when the module is affixed to the vehicle. The armor element can be generally planar and oriented parallel to the hull to shield the buoyant element and the hull from ballistic threats travelling transverse to the plane of the hull. Positioning the armor element on the exterior side of the buoyant element allows for the use of active armor without the risk of damaging the buoyant element and comprising the performance of the buoyant element.
- In one aspect, the buoyant element of each module can be sized to provide a buoyancy force offsetting only the weight of the corresponding armor element. In another aspect, the buoyant element can have a larger size to provide a buoyancy force greater than necessary to offset the weight of the armor element of that module. In this configuration, the surplus buoyancy force generated by the buoyant element partially offsets the overall weight of the vehicle. The size of the buoyant element can be selected according to the intended mounting location on the hull of the particular module. Modules having smaller buoyant elements can be positioned on portions of the hull where space is limited, such as on the undercarriage of the vehicle. Similarly, modules having larger buoyant elements can be positioned on portions of the hull where space is less of a premium, such as on the sides of the hull.
- In one aspect, the armor elements can be generally planar such that positioning a plurality of armored modules end-to-end on the hull aligns the horizontal and/or vertical edges of the armor elements to create a nearly continuous armor layer. Similarly, aligning the armor elements can also align the buoyant elements to create a nearly continuous buoyant layer between the armor layer and the hull. In this configuration, the armor appliqué system can further comprise an adjustable mounting assembly for adjusting the horizontal position of the armored modules to minimize ballistic gaps between the armor elements.
- A method of supplementing the integrated armor of an amphibious vehicle having an exterior hull can comprise providing a plurality of armored modules that each have an armor element and a buoyant element. The method can further comprise positioning each of the armored modules on the hull such that the buoyant element is positioned between the armor element and the hull.
