Abstract

An underbody kit for a vehicle having an outer body shell defining a cavity, at least one explosive device secured to the outer body shell within the cavity, and wherein the underbody kit is constructed and arranged to counteract both a blast event near the vehicle and a penetrator event.

First claim

What is claimed is:

1. An underbody kit for a vehicle comprising:
an outer body shell, wherein the outer body shell includes a cavity defined within the outer body shell;
at least one explosive device secured to the outer body shell within the cavity; and
wherein the cavity is constructed and arranged to provide a vertical space for energy from a blast to dissipate before encountering a hull of a vehicle to counteract a blast event and the at least one explosive device is passive and is constructed and arranged to detonate upon impact from a penetrator to counteract a penetrator event.

2. The underbody kit of claim 1 wherein the outer body shell comprises a first side wall, a second side wall, wherein the first side wall and the second side wall meet at a first end, a top wall attached to each of the first side wall and the second side wall, a first end plug secured to the first side wall, the second side wall, and the top wall, and a second end plug positioned opposite of the first end plug and secured to the first side wall, the second side wall, and the top wall, wherein the first end plug and the second end plug are constructed and arranged so that when the at least one explosive device explodes, the first end plug and the second end plug are pushed from the remaining outer body shell to open and vent the outer body shell.

3. The underbody kit of claim 1 wherein the at least one explosive device comprises a plurality of reactive armor explosive devices.

4. The underbody kit of claim 1 wherein the at least one explosive device is arranged as an array of explosive devices.

5. The underbody kit of claim 3 wherein the plurality of reactive armor explosive devices are arranged to explode in at least two different directions.

6. The underbody kit of claim 3 wherein the array is at least a two-by-two array of the reactive armor explosive devices.

7. The underbody kit of claim 1 wherein the at least one explosive device comprise a first group of explosive devices positioned on a first side of a centerline and a second group of explosive devices positioned on a second side of the centerline; wherein the first group of explosive devices is configured to explode in a first direction and the second group of explosive devices is configured to explode in a second direction; and wherein the first direction is different than the second direction.

8. The underbody kit of claim 1 wherein the centerline corresponds to a centerline of the vehicle along a longitudinal axis of the vehicle.

9. The underbody kit of claim 1 wherein the outer body shell comprises at least one of steel, aluminum, or titanium.

10. The underbody kit of claim 1 wherein the outer body shell is configured to be attached to the vehicle by at least one mechanical fastener.

11. The underbody kit of claim 1 wherein the underbody kit is constructed and arranged to span a length of a passenger compartment of the vehicle.

12. The underbody kit of claim 1 wherein the underbody kit is constructed and arranged to be removeable from the vehicle.

13. A method of protecting a vehicle against both a blast event and a penetrator event comprising:
producing an underbody kit, wherein the underbody kit includes an outer body shell defining a cavity within the outer body shell and at least one explosive devices disposed within the cavity and secured to the outer body shell; wherein the outer body shell provides a space for energy from a blast to dissipate before encountering a hull of a vehicle to protect the vehicle from the blast event and the at least one explosive device is passive and detonates upon impact from a penetrator to counteract the penetrator to protect the vehicle from the penetrator event; and
attaching the underbody kit to the vehicle.

14. The method of claim 13 further comprising venting of the outer body shell when the at least one explosive device explodes by opening of a first end plug and a second end plug.

15. The method of claim 13 further comprising:
removing the underbody kit for servicing and reattaching the underbody kit to the vehicle.

16. The method of claim 13 further comprising:
attaching the underbody kit to the vehicle so that the underbody kit spans a length of a passenger compartment of the vehicle.

17. The method of claim 13 wherein the at least one explosive device is formed as an array of individual explosive devices.

18. The method of claim 17 wherein the array of individual explosive devices contains a centerline with a first group of individual explosive devices located on a first side of the centerline and a second group of individual explosive devices located on a second side of the centerline, and wherein the centerline corresponds to a centerline of the vehicle along a longitudinal axis of the vehicle.

19. The method of claim 18 wherein the first group of individual explosive devices are constructed and arranged to explode in a first direction and the second group of individual explosive devices are constructed and arranged to explode in a second direction that is different than the first direction.

20. An underbody kit for a vehicle comprising:
an outer body shell, wherein the outer body shell defines an internal cavity;
at least one explosive device secured to the outer body shell within the internal cavity;
a first end cap secured to a first end of the outer body shell and a second end cap secured to a second end of the outer body shell;
wherein the underbody kit is constructed and arranged so that energy from a blast event is dissipated in the internal cavity before reaching a hull of a vehicle during a blast event, and the at least one explosive device detonates upon impact from a penetrator that passes through the outer body shell during a penetrator event, and wherein the first end cap and the second end cap are pushed from the outer body shell upon detonation of the at least one explosive device, venting the outer body shell so that the outer body shell remains attached to the vehicle during the penetrator event.
