Abstract
Official abstract text for this publication.
A shock mitigation casing includes a monolithic body made from a solid material. The monolithic body includes a first wall, a second wall spaced apart from the first wall, and axial end walls contiguous with the first wall and the second wall. A chamber is defined between the walls. A powder fills the chamber. The powder is a powdered form of the solid material.
First claim
Opening claim text (preview).
What is claimed is: 1. A shock mitigation casing, comprising: a monolithic body being made from a solid material, said monolithic body comprises a first wall, a second wall spaced apart from said first wall, and axial end walls contiguous with said first wall and said second wall, wherein a chamber is defined between said first wall, said second wall, and said axial end walls; and a powder filling said chamber, said powder is a powdered form of said solid material, wherein the chamber is a continuous, annular shaped chamber. 2. The shock mitigation casing as in claim 1 , wherein said powder is selected from a group of powders susceptible to being fused to a solid form thereof via powder bed fusion. 3. The shock mitigation casing as in claim 1 , wherein said powder is selected from one of a metal powder, a ceramic powder, and a plastic powder. 4. The shock mitigation casing as in claim 3 , wherein said metal powder comprises a metal selected from the group of aluminum, titanium, steel, stainless steel, Inconel, tungsten, copper, brass, zirconium, magnesium, tantalum, and alloys thereof. 5. The shock mitigation casing as in claim 3 , wherein said plastic powder comprises a thermoplastic plastic material. 6. A shock mitigation casing for a warhead, comprising: an open-ended and hollow monolithic tube being made from a solid material, said monolithic tube comprises an inner radial wall, an outer radial wall spaced apart from said inner radial wall, and axial end walls contiguous with said inner radial wall and said outer radial wall, wherein an annular chamber is defined between said inner radial wall, said outer radial wall, and said axial end walls; and a powder filling said annular chamber, said powder is a powdered form of said solid material, wherein the annular chamber is a continuous, annular shaped chamber. 7. The shock mitigation casing as in claim 6 , wherein said powder is selected from a group of powders susceptible to being fused to a solid form thereof via powder bed fusion. 8. The shock mitigation casing as in claim 6 , wherein said powder is selected from one of a metal powder, a plastic powder, and a ceramic powder. 9. The shock mitigation casing as in claim 8 , wherein said metal powder comprises a metal selected from aluminum, titanium, steel, stainless steel, Inconel, tungsten, copper, brass, zirconium, magnesium, tantalum, and alloys thereof. 10. The shock mitigation casing as in claim 8 , wherein said plastic powder comprises a thermoplastic plastic material.
