This Application hereby claims the priority of United Kingdom Patent Application No. 1002246.5 filed Feb. 10, 2010 and entitled “ARMOR SYSTEM,” filed by NP Aerospace Limited on behalf of Roger Arthur Terrence Medwell and David Charles Batstone, which UK Application is hereby incorporated herein by reference in its entirety.
This invention relates to a modular armor system.
It is known to enhance the resistance to projectiles of a vehicle by fixing multilayered armor to the vehicle hull. In doing so it is important to balance the required threat-resistance with the increased weight and bulk. Generally the armor is permanently attached to the vehicle, which leads to a lack of versatility.
It is an aim of the invention to provide armor with a modular capability allowing easier armoring of vehicles of different dimensions as well as swift repairs and changes to the level of armor in the field.
The present invention provides an armor panel assembly comprising a set of bolts for attaching to a vehicle hull, an inner panel demountably attached to the bolts, and at least one outer panel demountably attached to the inner panel.
A support panel may be provided for attaching the bolts, which may be in the form of spacers, to the hull. Brackets may be provided for mounting the support panel to the hull.
Outer brackets may be provided for attaching the outer panel(s) to the inner panel. The outer panel may be formed with recesses accommodating the outer brackets.
Outriggers may be provided for supporting bar armor on an outer side of the armor panel.
The materials of the panels are selected from known by those skilled in the art as affording protection from blast waves, spall, bullets, fragments, etc. Thus they may include composites, polymers, ceramics (e.g. tiled ceramics) and metals.
The invention also provides a kit of parts for forming a vehicle armor panel, the kit comprising a set of bolts for attaching to a vehicle hull, an inner panel for demountable attachment to the bolts, at least one outer panel, and outer brackets for demountably attaching the outer panel to the inner panel.
The invention will now be described in more detail, by way of example only, with reference to the accompanying drawings, in which:
Spacers 5 attach the inner panel 2 to the support panel 1. The spacers 5 are in the form of integrally cast bolts having enlarged hexagonal sections 5h that maintain a space between the inner panel 2 and the support panel 1 as well as round sections 5r extending through suitable holes in these panels 1, 2. The inner panel 2 is screwed to the spacers or bolts 5 by means of screws 6.
The screws 6 also retain outer brackets 7 in the form of elongate plates 7 on the inner panel 2. These brackets include bolts 8 extending through aligned holes in both outer panels 3, 4. The first inner panel 3 has recesses 3r accommodating the brackets 7. Nuts 9 secure the outer panels to the bolts 8.
The support panel 1 is mounted to the vehicle hull H by means of first support brackets 10 and second support brackets 11, only one of each kind of bracket being depicted. First support brackets 10 have an inverted V-shaped recess whilst second support brackets 11 are bar-shaped.
The support panel 1 is provided with a lift handle 12. It is also fitted with a number of outriggers 13 for supporting external bar armor.
In order to armor a vehicle, the armor plate is assembled as shown in
The second support brackets 11 are attached to the vehicle hull H or to a bar thereon.
The armor of the invention provides protection against explosively formed projectiles. When there is a low likelihood of these, the outer e.g. ceramic layers 3, 4 can still provide protection against small arms fire. It is possible to remove the inner and outer panels and then remount the outer panels 3, 4 on the spacers 5 without the inner panels 2 to save weight. A further advantage of the invention is that repairs can be carried out rapidly in the field, with damaged panels being exchanged and intact panels retained.
An armor panel assembly may comprise a set of bolts or spacers 5 for attaching to a vehicle hull H, an inner panel 2 demountably attached to the bolts or spacers 5, and at least one outer panel 3, 4 demountably attached to the inner panel 2. The assembly may also include a support panel 1 for attaching the bolts or spacers 5 to the hull H, and may further include brackets 10, 11 for mounting the support panel 1 to the hull H. The assembly may include outer brackets 7 for attaching the outer panel(s) 3, 4 to the inner panel 2, and the outer panel 3, 4 may be formed with recesses accommodating the outer brackets 7. The assembly may include outriggers 13 for supporting bar armor on an outer side of the armor panel. The bolts or spacers 5 may comprise spacers 5 having enlarged portions for spacing the inner panel 2 from the hull H, and the enlarged portions may be of non-circular cross section.
A kit of parts for forming a vehicle armor panel assembly may comprise a set of bolts or spacers 5 for attaching to a vehicle hull H , an inner panel 2 demountably attachable to the bolts or spacers 5, and at least one outer panel 3, 4 demountably attachable to the inner panel 2. The kit of parts may include outer brackets 7 for attaching the outer panel(s) 3, 4 to the inner panel 2, and the outer panel 3, 4 may be formed with recesses for accommodating the outer brackets 7. The kit of parts may include outriggers 13 for supporting bar armor on an outer side of the armor panel. The bolts or spacers 5 may comprise spacers 5 having enlarged portions for spacing the inner panel 2 from the hull H, and the enlarged portions may be of non-circular cross section.
An armor panel assembly may comprise: a support panel 1 for attaching to a vehicle hull H; brackets 10, 11 for mounting the support panel 1 to the vehicle hull H; a set of bolts or spacers 5 for attaching to the support panel 1, the bolts or spacers 5 having an enlarged section one end of which is at the support panel 1; an inner panel 2 demountably attached to the bolts or spacers 5 at the other end of the enlarged section thereof, and at least one outer panel 3, 4 demountably attached to the inner panel 2. The support panel 1 may be aluminum, the inner panel 2 may be polymer or composite, and the at least one outer panel 3, 4 may be ceramic or composite. The enlarged section of the bolts or spacers 5 may be a hexagonal section 5h, the bolts or spacers 5 may further have a round section 5r adjacent the enlarged hexagonal section 5h , wherein the round section 5r receives screws 6 attaching the inner panel 2 thereto. The assembly may include outer brackets 7 for attaching the outer panel(s) 3, 4 to the inner panel 2. The outer panel 3, 4 may be formed with recesses 3r accommodating the outer brackets 7. The assembly may further include outriggers 13 for supporting bar armor on an outer side of the armor panel assembly.
Modifications which do not depart for the claims will readily occur to the skilled reader. For example, there could be two inner panels with or without spacing therebetween. The ceramic layer(s) could be replaced by various other layers known in the art, and one or more additional layers—either demountable or fixed to another layer—of polymer, ceramic, glass or metallic materials could be added.
