US12498198 - Energetic material container having a heavy inert gas insulating layer

Heavy inert gas insulation layer(s) are provided for containers configured to contain components that include an energetic material. The heavy inert gas insulation layer delays desensitization or inhibits premature reaction of the energetic material due to high external temperatures. The layers may be formed in hollow walls of the container itself or as inserts that are attached to the container. An inert gas fills a sealed void space in the walls or the insert. The inert gas has a density of at least 1.5 Kg/m 3 and a thermal conductivity (Tcond_gas) of no greater than two-thirds of a thermal conductivity of air (Tcond_air) to form the heavy inert gas insulation layer. The inert gas may be Argon, Krypton, Xenon or a synthetic gas and is suitably held at a pressure of 760 Torr (1 atmosphere) or greater at sea level.

The patent describes an insulated container for energetic materials that incorporates a heavy inert gas insulation layer to prevent premature reactions due to high temperatures. This layer is formed within the hollow walls of the container or as separate inserts, utilizing gases such as Argon, Krypton, or Xenon to enhance thermal protection.

Claim 1

1 . An insulated container, comprising: a hollow metal shell having inner and outer walls that define a sealed void space therein; a component including an energetic material, said component positioned inside the hollow metal shell behind its inner walls; internal support features that engage one or more physical features of the component to support the component inside the hollow metal shell; and an inert gas inside the sealed void space, the inert gas having a density of at least 1.5 Kg/m 3 and a thermal conductivity (Tcond_gas) of no greater than two-thirds of a thermal conductivity of air (Tcond_air) to form a heavy inert gas insulation layer to delay desensitization or inhibit premature reaction of the energetic material due to high external temperatures. a hollow metal shell having inner and outer walls that define a sealed void space therein; a component including an energetic material, said component positioned inside the hollow metal shell behind its inner walls; internal support features that engage one or more physical features of the component to support the component inside the hollow metal shell; and an inert gas inside the sealed void space, the inert gas having a density of at least 1.5 Kg/m 3 and a thermal conductivity (Tcond_gas) of no greater than two-thirds of a thermal conductivity of air (Tcond_air) to form a heavy inert gas insulation layer to delay desensitization or inhibit premature reaction of the energetic material due to high external temperatures.
