Embodiments include a heat sink cell comprising a first reservoir having a first volume of space and a first material stored in the first volume of space. The first material provides a first heat sink thermal operating range for the transfer of heat. The cell comprises a second reservoir and a second material stored in the second reservoir. A shape memory alloy (SMA) closes an opening of the second reservoir. The SMA is responsive to a temperature change of the first material or external sources to automatically open the opening so that the first material or the second material spontaneously pass through the opening to cause an endothermic reaction or an exothermic reaction between the first material and the second material to create a second heat sink thermal operating range different from the first heat sink thermal operating range. Embodiments also include a system and method of dual-mode passive thermal management.

A device for inhibiting inadvertent initiation of a munition includes a sorbing refrigeration device adapted to at least partially surround an energetic material of the munition. A container includes an energetic material and a sorbing refrigeration device at least partially surrounding the energetic material. A method for inhibiting an inadvertent initiation of a munition includes cooling an energetic material of the munition by sorption refrigeration.

An apparatus for launching a vehicle includes a bag and an inflator in fluid communication with the bag, the inflator configured to generate a gas to inflate the bag. The apparatus is operable to launch the vehicle. A method for launching a vehicle includes the step of providing an apparatus for launching the vehicle, the apparatus comprising a bag and an inflator in fluid communication with the bag. The method further includes the step of activating the inflator, such that a gas flows from the inflator, and the step of inflating the bag with the gas to launch the vehicle.
