Apparatus comprising armor
An armor that is used, for example, in multi-cell missile launchers is disclosed. In some embodiments, the armor includes three layers. The inner-most layer undergoes explosive welding when exposed to a pressure wave from an explosion. An intermediate layer in-elastically deforms when exposed to the explosion. The third and outer-most layer includes a plurality of elongated, pressurized tubes that contain fire retardant, among other chemicals. Silicone gel is interposed between the tubes.
1. An apparatus comprising armor, wherein said armor comprises:
a first layer, wherein said first layer comprises a first structural arrangement that undergoes explosive welding when exposed to an explosion;
a second layer, wherein said second layer comprises a second structural arrangement that in-elastically deforms when exposed to said explosion; and
a third layer, wherein said third layer comprises a physical adaptation for retarding fire due to said explosion.
2. The apparatus of claim 1 wherein said first structural arrangement comprises:
a spline; and
a plurality of fins that depend from said spline, wherein said fins are arranged to collapse toward said spline when exposed to a pressure wave from said explosion.
3. The apparatus of claim 1 wherein at least a portion of said first layer is characterized by an increase in hardness due to said explosive welding.
4. The apparatus of claim 3 wherein, relative to its pre explosively-welded condition, said explosively-welded first layer is characterized by an improved ability to stop fragments from said explosion.
5. The apparatus of claim 1 wherein said second structural arrangement comprises a sandwich configuration.
6. The apparatus of claim 5 wherein said sandwich configuration comprises:
(i) two spaced-apart beams; and
(ii) a plurality of cross members, wherein said cross members are disposed between said beams and depend therefrom.
7. The apparatus of claim 6 wherein said cross members depend from said beams at a non-orthogonal angle.
8. The apparatus of claim 1 wherein said third layer comprises a plurality of elongated pressurized tubes, wherein said physical adaptation comprises flame-retardant liquid that is disposed in said pressurized tubes.
9. The apparatus of claim 8 wherein said third layer further comprises a thermally-stable gel, wherein said thermally-stable gel is interposed between said tubes.
10. The apparatus of claim 8 wherein said tubes contain at least one material selected from the group consisting of sand, clorofluorocarbons, argon, nitrogen, and silicon gel.
11. The apparatus of claim 1 wherein said apparatus comprises a missile launcher having a launcher body and a plurality of launch cells defined within said launcher body, wherein said armor is disposed within at least some of said launch cells.
12. The apparatus of claim 11 wherein each of said launch cells is defined by a launch-cell wall, and further wherein:
said third layer is proximal to said launch-cell wall;
said first layer is distal to said launch-cell wall; and
said second layer is situated between said first layer and said third layer.
13. An apparatus comprising armor, wherein said armor is physically adapted to achieve an enhanced ability to prevent fragments that result from an explosion from penetrating said armor, wherein enhancement occurs as a result of said armor being exposed to a pressure wave from said explosion.
14. The apparatus of claim 13 , wherein said armor is characterized by a structural arrangement that undergoes explosive welding when exposed to said pressure wave.
15. The apparatus of claim 13 wherein said apparatus comprises a missile launcher having a plurality of launch cells, wherein said armor is disposed within at least some of said launch cells.
16. An apparatus comprising armor, wherein said armor comprises:
a first layer that is physically adapted to explosively weld when exposed to a pressure wave from an explosion; and
a second layer, wherein said second layer comprises:
a plurality of elongated, pressurized tubes, and
a thermally-stable gel interposed between said sealed tubes.
17. The apparatus of claim 16 wherein said tubes contain a fire retardant.
18. The apparatus of claim 16 wherein said apparatus comprises a missile launcher having a plurality of launch cells, wherein said armor is disposed within at least some of said launch cells.
