The invention claimed is: 1. A reactive armor element for protection against various types of threats, comprising a casing fitted with an outer cover plate, and at least one sandwich element extending behind the plate; said sandwich element comprising at least one pair of substantially fiat plates
The invention claimed is: 1. A reactive armor element for protection against various types of threats, comprising a casing fitted with an outer cover plate, and at least one sandwich element extending behind the plate; said sandwich element comprising at least one pair of substantially fiat plates with an energetic material applied there between, wherein said energetic material is a non-explosive, non Class 1 material in the form of a flexible and pliable sheet, and comprising an oxidizer and a fuel agent, which together with a suitable catalyst material and a silicone binder provide the resultant non-explosive energetic material, constitute a few microsecond discharge gas generator. 2. A reactive armor according to claim 1, wherein said oxidizer is selected from nitrates, nitrites chromates, dichromates, perchlorates and chlorates; said catalytic material is a transition metal oxide; and wherein said fuel is a binder. 3. A reactive armor according to claim 2, wherein said oxidizer is sodium nitrate (NaNO3), and said catalytic material is Fe2O3. 4. A reactive armor according to claim 3, wherein the amount of said oxidizer does not exceed about 80%; the amount of said catalytic material does not exceed about 2%; and the amount of said fuel does not exceed about 50%. 5. A reactive armor according to claim 1, wherein the energetic material comprises hollow microballoons; said hollow microballoons having a diameter of about 40 μm. 6. A reactive armor according to claim 5, wherein the hollow microballoons are made of a material selected from the group of materials comprising, among others, glass, plastic material, metallic and ceramic materials. 7. A reactive armor according to claim 6, wherein the amount of said microballoons does not exceed about 10%. 8. A reactive armor element according to claim 1, wherein the plates are made of inert material. 9. A sandwich element for a reactive armor, comprising at least one pair of substantially flat plates with a non-explosive, non Class 1 energetic material applied between said at least one pair of plates, wherein said energetic material is in the form of a flexible and pliable sheet, and comprising an oxidizer and a fuel agent, which together with a catalyst material and a silicone binder provide the resultant non-explosive energetic material, constituting a few microsecond discharge gas generator. 10. A sandwich element according to claim 9, wherein said oxidizer is selected from nitrates, nitrites chromates, dichromates, perchlorates and chlorates; said catalytic material is a transition metal oxide; and wherein said fuel is a binder. 11. A sandwich element according to claim 10, wherein said oxidizer is sodium nitrate (NaNO3); and said catalytic material is Fe2O3. 12. A sandwich element according to claim 11, wherein the amount of said oxidizer does not exceed about 80%; the amount of said catalytic material does not exceed about 2%; and the amount of said fuel does not exceed about 50%. 13. A sandwich element according to claim 9, wherein the energetic material comprises hollow microballoons for increasing reaction rate thereof; said hollow microballoons having a diameter of about 40 μm. 14. A sandwich element according to claim 13, wherein the hollow microballoons are made of a material selected from the group of materials comprising, among others, glass, plastic material, metallic and ceramic materials. 15. A sandwich element according to claim 14, wherein the amount of said microballoons does not exceed about 10%. 16. An energetic material according to claim 14, wherein said oxidizer is sodium nitrate (NaNO3); and said catalytic material is Fe2O3.
