초록

The present invention relates to decoys for heat-seeking missiles and methods of producing and using the same. The decoys axe designed to be kinematic or pseudo-kinematic, producing one or more infra-red radiation emitting clouds that give the appearance of a moving infra-red target in the airspace in which the decoy has been released.

1. A decoy for an infra-red radiation seeking device that comprises: a) an anchoring body;b) two or more bundles of pyrophoric elements;c) straps that bind at least two of the bundles to the anchoring body; andd) two or more pyrophoric bodies, wherein each pyrophoric body heats up upon exposure to air and melts or burns at least one strap that binds at least one bundle to said anchoring body thereby causing said at least one strap to break or fail resulting in the release of said at least two bundles from said anchoring body and from said decoy after said decoy has been released from a target, further wherein:(i) each bundle of pyrophoric elements forms a cloud of pyrophoric elements shortly after release from the decoy and said cloud of pyrophoric elements emits infra-red radiation; and(ii) at least some of the pyrophoric elements comprise a pyrophoric coating on a supporting body, said pyrophoric coating containing at least one pyrophoric powder and a binder. 2. The decoy of claim 1, wherein one of said bundles of pyrophoric elements contains pyrophoric elements that are made of a different material or have a different composition than the pyrophoric elements of another one of the bundles in the decoy. 3. The decoy of claim 1, wherein at least one of the bundles of pyrophoric elements also contains pyrophoric powder. 4. The countermeasure of claim 3, wherein the decoy also contains pyrophoric powder located either: (a) inside at least one of the bundles of pyrophoric elements, or(b) on top of at least one of the pyrophoric elements; or(c) between two of the bundles of pyrophoric elements. 5. The decoy of claim 1, wherein at least one of the bundles of pyrophoric elements, before release from the decoy, is attached to one or more ribbons of pyrophoric material that unfold when the top of the bundle is exposed to the air and, after unfolding, said ribbons generate infra-red radiation. 6. The decoy of claim 1, wherein at least one of said pyrophoric bodies is a flat plate or foil that is located on the upper surface of one of said bundles of pyrophoric elements and in contact with or located close to said at least one strap that binds the bundle to the anchoring body wherein said flat plate or foil has at least one hole that passes through said flat plate or foil so that air can pass through said at least one hole and contact a bottom surface of said flat plate or foil that is not in contact with and does not face said at least one strap, further wherein a portion of said bottom surface of said flat plate or foil is in contact with a spacer that is shaped so as to permit air to access the portions of the bottom surface of said flat plate or foil that are not in contact with said spacer. 7. The decoy of claim 1, wherein said two or more pyrophoric bodies are disposed within said decoy so that each of said bundles of pyrophoric elements that are bound to the anchoring body by at least one of said straps contain at least one pyrophoric body that is located on the upper surface of the bundle and is in contact with or located close to said at least one strap that binds the bundle to the anchoring body. 8. The decoy of claim 1, wherein at least one of said pyrophoric bodies is a flat plate or foil that is located on the upper surface of one of said bundles of pyrophoric elements and in contact with or located close to said at least one strap that binds the bundle to the anchoring body wherein said flat plate or foil has an upper surface and a bottom surface and the upper surface is in contact with or located close to said at least one strap that binds the bundle to the anchoring body and the bottom surface is not in contact with and does not face said at least one strap, further wherein a portion of said bottom surface of said flat plate or foil is in contact with a spacer that is shaped so as to permit air to access the portions of the bottom surface of said flat plate or foil that are not in contact with said spacer. 9. The decoy of claim 1, wherein for at least some of the pyrophoric elements that comprise a pyrophoric coating on a supporting body, said pyrophoric coating also contains at least one ignitable powder in addition to said at least one pyrophoric powder and said binder. 10. The decoy of claim 9, wherein the pyrophoric elements that comprise a pyrophoric coating comprising at least one ignitable powder in addition to said at least one pyrophoric powder and said binder are formed by applying a dispersion containing the pyrophoric powder, the ignitable powder, the binder and a solvent or carrier to at least a portion of the surface of the supporting body in a nitrogen, reducing or inert atmosphere and then removing at least a portion of the solvent or carrier. 11. The decoy of claim 10, wherein the supporting body is in the form of a foil or web. 12. The decoy of claim 1, wherein the pyrophoric elements that comprise a pyrophoric coating on a supporting body are formed by applying a dispersion containing the pyrophoric powder, the binder and a solvent or carrier to at least a portion of the surface of the supporting body in a nitrogen, reducing or inert atmosphere and then removing at least a portion of the solvent or carrier. 13. The decoy of claim 12, wherein the supporting body is in the form of a foil or web. 14. A countermeasure for an infra-red radiation seeking device comprising, before deployment from a target: (a) a container; and(b) a decoy, wherein said decoy is disposed in said container and said container is hermetically sealed, further wherein said decoy comprises: (i) two or more bundles of pyrophoric elements;(ii) an anchoring body;(iii) straps that bind at least two of the bundles to the anchoring body; and(iv) two or more pyrophoric bodies; wherein a) said two or more bundles of pyrophoric elements comprise a first bundle and a second bundle;b) each pyrophoric body heats up upon exposure to air and melts or burns at least one strap that binds at least one bundle to said anchoring body thereby causing the release of said at least two bundles from said anchoring body and from said decoy after said decoy has been released from a target;c) each of said bundles forms a cloud of pyrophoric elements shortly after release from the decoy and said cloud produces infra-red radiation; andd) at least some of the pyrophoric elements comprise a pyrophoric coating on a supporting body, said pyrophoric coating containing at least one pyrophoric powder and a binder. 15. The countermeasure of claim 14, wherein the decoy also contains one or more ribbons of pyrophoric material that are located between the bundles and are in a folded or compressed state, further wherein the one or more ribbons are attached to the top surface of one or more of the bundles or are attached to spacers or plates that are attached to the top surface of the one or more bundles. 16. The countermeasure of claim 14, wherein for at least some of the pyrophoric elements that comprise a pyrophoric coating on a supporting body, said pyrophoric coating also contains at least one ignitable powder in addition to said at least one pyrophoric powder and said binder. 17. A method of attracting or decoying an infra-red radiation seeking device away from a target comprising ejecting a decoy from the target wherein said decoy comprises: a) an anchoring body;b) two or more bundles of pyrophoric elements;c) straps that bind at least two of the bundles to the anchoring body; andd) two or more pyrophoric bodies, wherein each pyrophoric body heats up upon exposure to air and melts or burns at least one strap that binds at least one bundle to said anchoring body thereby causing said at least one strap to break or fail resulting in the release of said at least two bundles from said anchoring body and from said decoy after said decoy has been released from a target, further wherein:(i) each of the bundles forms a cloud of pyrophoric elements shortly after release from the decoy and said cloud of pyrophoric elements produce infra-red radiation; and(ii) at least some of the pyrophoric elements comprise a pyrophoric coating on a supporting body, said pyrophoric coating containing at least one pyrophoric powder and a binder. 18. The method of claim 17, wherein for at least some of the pyrophoric elements that comprise a pyrophoric coating on a supporting body, said pyrophoric coating also contains at least one ignitable powder in addition to said at least one pyrophoric powder and said binder.
