Downed Airman Power Source (DAPS) for Inclusion into the RSSK-8A Aircraft Ejection Seat to be used by Downed Pilots for Environmental Anti-Exposure Protection.
Abstract
A source of heat to extend survival time during search and rescue operations for downed airman in cold environments. The heat source is derived from the catalytic combustion of propane fuel with resultant release of chemical energy in the form of heat. The heat is picked up by a heat transfer fluid in heat exchangers and pumped to the man via umbilicals on the DAPS to a tubulated undergarment worn by the airman where the heat is dumped. The system is a closed loop and therefore, after dumping its heat the fluid is returned to the DAPS where it picks up additional heat. The system is capable of supplying up to 250 thermal watts to the airman at fluid temperature of approximately 100 to 105F. The fluid flow rate is approximately .25 to .30 gallons per minute. The system also has a 12 VDC DC-DC converter used to power an emergency flasher or transmitter.
