Waste Heat Recovery of Rocket Motors for Reduction of Battery Weight

This proposal describes a program by Advanced Cooling Technologies, Inc. (ACT) that will develop a missile engine waste heat recovery system for recharging the batteries of a missile. The proposed system will use heat pipes to transfer the waste energy from the insulation around a missile engine. The heat pipes will be covered with thermoelectrics at their condenser end where the waste energy will be converted to electric power for charging the missile batteries. Bonded to the thermoelectrics will be a phase change material which will dissipate any additional waste energy not converted to electric power. This system will be efficient in design with no moving parts and when fully optimized have a mass less than the 5 kg weight specification in the solicitation.
