Cruise missile weapon active hazard mitigation system

A mitigation control system is arranged in an environment containing an energetic material and includes an abnormal temperature sensor for detecting an abnormal temperature of the environment, a power source that is mechanically actuated by the abnormal temperature sensor when the abnormal temperature exceeds a predetermined abnormal temperature threshold, a mitigation controller that is actuated by the power source, and a plurality of local temperature sensors that are communicatively coupled to the mitigation controller and are arranged for detecting critical temperatures in specific regions of the environment. The mitigation controller executes a mitigation action when one of the critical temperatures exceeds a predetermined critical temperature threshold for the corresponding specific region.

Thermal energy absorbing structures
11150065 · 2021-10-19 · ·

Thermally-sensitive hardware is at least partially enclosed within a container in which reactants for a solid-solid endothermic chemical reaction are disposed, surrounding at least a portion of the thermally-sensitive hardware. The reactants or a structure including the reactants are positioned between the thermally-sensitive hardware and a heat source, such as an external surface of a missile traveling through atmospheric gases at extremely high speed and experiencing extreme frictional heating. The reactants absorb heat during the solid-solid endothermic reaction to thermally protect the thermally-sensitive hardware. The reactants are preferably selected to absorb heat of at least 5 kilo-Joules per gram (kJ/g) during the solid-solid endothermic chemical reaction.
