Enhancement of solid explosive munitions using reflective casings
A solid explosive munition casing for an explosive charge, the inner surface of the casing including a material that is highly reflective in the optical and infrared spectrum. Through this reflectivity, electromagnetic radiation generated by the detonation process is redirected back into the interior of the munition to increase its explosive output.
1. A casing for a solid explosive munition comprising a casing wall for enclosing a munition, an inner surface of said casing wall including an optical reflecting layer that is highly reflective in the optical and infrared spectrum, said optical reflecting layer including a separate liner element and configured to increase explosive performance output of said munition by reflecting electromagnetic radiation generated by detonation of the munition.
2. The casing as set forth in claim 1 , wherein said optical reflecting layer includes sheeting of at least one of metal, ceramic or plastic.
3. The casing as set forth in claim 2 , wherein said optical reflecting layer includes sheeting of a reflecting metal having a low emissivity.
4. The casing as set forth in claim 3 , wherein the reflecting metal is selected from the group consisting of aluminum, lead, steel, tungsten, nickel and gold.
5. An encased solid explosive munition device comprising a casing and a charge enclosed by said casing, an inner surface of said casing including an optical reflecting layer that is highly reflective in the optical and infrared spectrum, said optical reflecting layer including a separate liner element and configured to reflect electromagnetic radiation generated by detonation of said munition device to increase explosive output performance.
6. The device as set forth in claim 5 , wherein said optical reflecting layer includes sheeting of at least one of metal, ceramic or plastic.
7. The device as set forth in claim 6 , wherein said optical reflecting layer includes sheeting of a reflecting metal having a low emissivity.
8. The casing as set forth in claim 7 , wherein the reflecting metal is selected from the group consisting of aluminum, lead, steel, tungsten, nickel and gold.
9. The casing as set forth in claim 1 , wherein said casing is generally cylindrical and includes longitudinally extending reinforcement members radially spaced along said casing wall, said reinforcement members made of a material stronger than a material of said casing wall.
10. An encased solid explosive munition device comprising a generally cylindrical casing and a charge enclosed by said casing, said casing having longitudinally extending reinforcement members being radially spaced along a casing wall and made of a material stronger than a material of said casing wall, an inner surface of said casing wall including an optical reflecting layer that is highly reflective in the optical and infrared spectrum, said optical reflecting layer configured to reflect electromagnetic radiation generated by detonation of said munition device to increase explosive output performance.
