This application claims the benefit of U.S. Provisional Patent Application Ser. No. 60/562,764, filed Apr. 16, 2004 by David J. Wolf et al. entitled “Field Retrofittable and Reconfigurable Lethal Threat Protection System for a Vehicle and Method,” which application is incorporated by reference herein.
FIELD OF THE INVENTIONThis invention relates generally to armoring, and more particularly to an armoring system for military land vehicles and other types of vehicles and structures.
BACKGROUND OF THE INVENTIONMilitary operations require many different types of land vehicles. One type of military land vehicle is a high speed, high mobility, reconnaissance vehicle, for example, a High Mobility Multipurpose Wheeled Vehicle (“HMMWV”). All types of military land vehicles may encounter various types of lethal threats, for example, ballistic threats, explosive threats, etc. Ballistic threats are presented by bullets and other projectiles; and explosive threats are presented by anti-tank mines, anti-personnel mines, claymores, improvised explosive devices (“IEDs”), etc. Explosive threats are often detonated by the pressure of one or more of the tires or wheels of the vehicle rolling over them or by remote detonation. Some explosive devices create a blast pressure for destructive incapacitive effect, whereas other explosive devices have a lower blast pressure and rely primarily on hundreds of flying shrapnel fragments for incapacitation effect. It is known to armor a perimeter of a vehicle to protect it from ballistic threats and to provide an underbody of the vehicle with blast shields to protect it from explosive threats. However, the type of protection chosen is determined by the threat perceived by a user.
There are many different models of the HMMWV; and as manufactured, an original equipment manufacture (“OEM”) HMMWV does not have armor or blast shields to protect occupants from lethal threats. Consequently, lethal threat protection systems using combinations of armor and blast shields have been developed for the OEM HMMWV, for example, see U.S. Pat. Nos. 5,663,520 and 4,326,445. In known lethal threat protection systems, the armor and blast shields are mounted on the vehicle by a supplier of the protection system, either at the supplier's factory or by the supplier's personnel or field technicians at a location other than the factory site. Further, there is a common characteristic of known protection systems, that is, the armor and blast shields are permanently applied to the vehicle. Although the armor and blast shields can be removed, a substantial and very costly restoration effort is generally required to restore the vehicle to its original unarmored use. Therefore, known lethal threat protection systems that have been installed on vehicles are most often considered permanent by their owners and users.
While the above approach has proven satisfactory, it does have some disadvantages. First, a HMMWV may not always be exposed to lethal threats; and it may be desirable to return the vehicle to its OEM use, that is, civilian, nonmilitary use. Thus, to burden a vehicle with a lethal threat protection system over its whole useful life is very costly in terms of vehicle operation, user comfort maintainability and vehicle life. Therefore, there is a need for a lethal threat protection system that is effective at providing explosive protection to its occupants but can also be readily removed from the vehicle when such protection is no longer necessary.
Another disadvantage of known permanent vehicle armoring systems is that such systems cannot be changed as changes in circumstances dictate. The exposure to lethal threats is not the same everywhere; but with known systems, there is only one practical way to deal with such variations, that is, apply the maximum armor to the vehicle, so that it can be used anywhere. Such an approach is, in many respects, costly and inefficient. Therefore, there is a need to permit a user of the vehicle armoring system to be able to reconfigure the armoring system to the user's current needs.
SUMMARY OF THE INVENTIONThe present invention provides a vehicle armoring system that may be installed in the field by a user. The vehicle armoring system of the present invention can also be quickly and cost effectively reconfigured and/or removed by the user. Thus, the vehicle armoring system of the present invention has the advantage of allowing a user to tailor the armoring system on the vehicle to changing perceived threats and circumstances. Further, the user is able to cost effectively return the vehicle to unarmored use.
One embodiment of the invention includes a field retrofitable and reconfigurable system that protects a vehicle occupant by providing pillar armor attachable to an outside vehicle surface after an OEM door and hinge are removed. An armored door of the system has a hinge, and fasteners extend through the hinge of the armored door; the pillar armor and an OEM pillar using holes other than the vehicle OEM holes. The armor fasteners, pillar armor and the armored door are removable from the vehicle to permit the OEM hinge and door to be reconnected to the OEM pillar by the OEM fasteners extending through the OEM holes.
More particularly, the system includes an A pillar reinforcement adapted to be located adjacent an inner surface of an OEM pillar. This A pillar reinforcement is typically secured in place by armor fasteners. The system further includes B pillar armor adapted to be attached to an OEM B pillar after removal of an OEM rear door hinge and an OEM rear door. To this end, armor fasteners extend through a hinge of an armored rear door, the B pillar armor and the OEM B pillar using holes other than the OEM holes in the OEM B pillar. The B pillar armor and the armored rear door are removable from the OEM B pillar and permit the OEM rear door to be reconnected to the OEM B pillar by fasteners that extend through the OEM holes in the OEM B pillar.
Additional rocker panel protection provided by the system includes rocker panel armor positioned on each side of the vehicle and adapted to be attachable with fasteners to a respective side extending from the A pillar armor to the rear wheel well below the armored door. The rocker panel may be removed from the vehicle.
Another or the same embodiment includes windscreen protection. The windscreen protection includes a ballistic resistant windscreen mounted in a frame adapted to be located in a peripheral channel that extends into a front surface of an OEM windscreen frame. Armor caps extend around a periphery of the frame, and armor fasteners extend through the armor caps and into holes in the OEM windscreen frame, other than the OEM holes. The armor fasteners, armor caps and the ballistic resistant windscreen are removable from the peripheral channel and permit the OEM windscreen to be remounted in the peripheral channel by the OEM fasteners that extend through the OEM holes.
Front underbody protection provided by an embodiment of the present invention includes a pair of reinforcing plates. Each of the reinforcing plates is adapted to be located adjacent one of two opposing side walls of a forward portion of the vehicle. The reinforcing plates are typically connected with fasteners to the vehicle. The underbody protection feature further includes a blast resistant shield adapted to cover external areas of the forward portion of the vehicle. The blast resistant shield is typically located between an anticipated source of a blast and the forward portion of the vehicle. Fasteners connecting the blast resistant shield to the vehicle are removable. This blast resistant shield feature absorbs energy and a pressure wave from a lethal threat by bending and deforming.
A rear wall protection feature on an embodiment includes armor adapted to be attachable with fasteners to a lowermost surface of a rear wheel well. The armor extends upward adjacent a forward surface of the rear wheel well. Fasteners and the armor are configured to be removable from the rear wheel well.
An embodiment further includes front armor adapted to be attachable with fasteners to the vehicle adjacent a forward surface of a forward position in which the lower legs and feet of an occupant are positioned. The fasteners and the forward armor are configured to be removable from the vehicle.
Where desired, armor includes a composite plate that includes a strike face that is constructed from softer metallic material than an inner metallic sheet. The relatively softer and tougher strike face of the composite plate mitigates dangers associated with penetration of lethal threats.
A method of attaching in the field retrofitable and reconfigurable lethal threat protection system includes removing at least one OEM component and drilling fastener holes in the vehicle that do not overlap or interfere with OEM holes. A component of the lethal threat protection system that substitutes for the OEM component is mounted using second fasteners and fastener holes. The second fasteners and component of the lethal threat protection system is subsequently removed, and the OEM component is thereafter reinstalled using the OEM holes.
Embodiments of the present invention thus allow a user to retrofit and reconfigure a combination of the components of the perimeter armor feature and/or the underbody blast protection features in the field. A user may readily reconfigure the components in response to a perceived threat change. The user may further remove any or all of the components of the system and reinstall OEM component using OEM fasteners and holes.
These and other objects and advantages of the present invention will become more readily apparent during the following detailed description taken in conjunction with the drawings herein.

As received from an OEM vehicle supplier, OEM fasteners extend through holes of an OEM hinge for an OEM door and then through OEM holes in the A pillar 55. The OEM fasteners are threaded into nuts welded or otherwise attached to a rear side of the OEM A pillar 55, thereby securing the left front OEM door to the OEM A pillar 55. The OEM fasteners are removed in order to remove the OEM left front and rear doors. In the Figs., the OEM doors have been removed; and the OEM windscreens that mount in an OEM windscreen frame 58 have also been removed.
The A pillar armor, A pillar reinforcements, B pillar armor, armored doors and rocker panel armor of the perimeter armor system 24 are substantially the same on both the left and right sides of the vehicle body 22; and therefore, only the left side of the perimeter armor system 24 will be described in detail. As shown in
Holes for mounting the hinge 56 are located by using A pillar armor 30 that has first holes that are alignable with OEM hinge holes on the OEM A pillar 55, which are used to mount the OEM left front door hinge. After removing the OEM left front door, the first holes in the A pillar armor 30 are located over the OEM hinge holes, and the A pillar armor 30 is mounted on the OEM A pillar 55 using the fixed nuts that are used to secure the OEM hinge. The A pillar armor 30 has second holes therein that locate holes for mounting the hinge 56 of the armored door 26. The A pillar armor 30 is used as a drill guide to drill holes through the vehicle body 22 and the OEM pillar 55 for mounting the hinge 56. It should be noted that the second holes in the A pillar armor 30 do not overlap the first holes. The A pillar armor 30 is then removed from the OEM A pillar 55.
As shown in
Using the washer plate 59, the holes in the hinge plate 61, the A pillar armor 30 and the bar 66 do not overlap any of the OEM holes in the OEM body 22 that are used to attach the OEM doors. Therefore, if it is desired to remove the armored door 26, the A pillar armor 30 and the A pillar reinforcement 32, the bolts 76 and double nuts 70 are removed, thereby releasing all of the armored components from the OEM vehicle body 22 and permitting the OEM doors to be reinstalled utilizing the OEM fasteners and OEM holes in the OEM body 22.

With known armoring systems, a portion of the vehicle skin is sandwiched between an armor plate and an aluminum composite plate to provide protection from spawling. With the present invention, the armored doors 26, 27, rocker panel armor 38 and A pillar armor 30 are made with a less brittle steel, for example, a tool steel, which provides protection from spawling; and therefore, the aluminum composite plate does not have to be used.
A more recent lethal threat is provided by an improvised explosive device (“IED”). An IED presents a threat that has the characteristics of both ballistic and blast threats. In order to protect against an IED threat, aluminum plates or shields are mounted on the vehicle. The aluminum sheet is about 0.750 inches thick and is often a commercially available 6061 aluminum.
In one embodiment, the aluminum sheet comprises a strike face of a composite plate that is mounted on vehicles to counteract threats, including IED's. The composite plate typically includes an inner sheet that comprises steel having a higher Rockwell C scale hardness rating than the aluminum sheet. The two sheets are typically mechanically fastened together, but may be welded or otherwise bonded together where advantageous. While aluminum presents certain advantages in specific applications, one skilled in the art will recognize that other metallic materials, i.e., those materials containing a metal, may be alternatively used for the strike face of the plate. As such, any metallic material used for the strike face of the embodiment will be softer than the inner sheet, that is, have a lower hardness rating. The inner sheet is typically less tough than the outer, strike face sheet, as well.
The relatively softer and tougher strike face of the composite plate produces unexpectedly advantageous results in mitigating the dangers associated with the penetration of IED's and other lethal threats. For instance, the softer and tougher strike face may absorb energy from a bullet, while the bullet pushes a plug size piece of the strike face away from the rest of the strike face sheet. The plug and bullet may consequently have insufficient force and focus to penetrate the relatively harder, inner sheet of the composite plate. Other advantages of the composite plate regard its manufacture and mounting onto the vehicle. Namely, the individual sheets of the composite plate are individually easier and cheaper to shape, transport, purchase and attach than a single sheet having a thickness comparable to the composite plate.
