Abstract
A system includes a guided munition having a housing. A first reservoir is defined within the housing holding a first chemical reactant. A second reservoir is defined within the housing, wherein the second reservoir holds a second chemical reactant configured to undergo an endothermic reaction with the first chemical reactant. A frangible barrier separates between the first and second reservoirs. The frangible barrier is configured to break under forces acting on the guided munition as the guided munition is fired from a weapon. An electronic device can be housed within the housing in thermal contact with at least one of the first reservoir and/or second reservoir for cooling the electronic device with an endothermic reaction upon mixing of the first and second chemical reactants.
Claims15
A system comprising:
- a guided munition including a housing;
- a first reservoir within the housing holding a first chemical reactant;
- a second reservoir within the housing, wherein the second reservoir holds a second chemical reactant configured to undergo an endothermic reaction with the first chemical reactant;
- and
- a frangible barrier separating between the first and second reservoirs, wherein the frangible barrier is configured to break under forces acting on the guided munition as the guided munition is fired from a weapon.
A guided munition including a housing with a cooling system inside the housing for cooling an internal electronic device inside the housing, wherein the cooling system is passively activated by firing the guided munition as a projectile, wherein a frangible barrier separates between first and second reservoirs, wherein the frangible barrier is configured to break under forces acting on the guided munition as the guided munition is fired from a weapon.
A method comprising:
- breaking a frangible barrier under forces acting on a housing of a guided munition as the guided munition is fired from a weapon;
- and
- mixing a first chemical reactant from a first reservoir within the housing with a second chemical reactant from a second reservoir within the housing to cause an endothermic reaction wherein breaking the frangible barrier brings the first and second chemical reactants into contact with one another.
