Downed Airman Power Source (DAPS) for Inclusion into the RSSK-1A Aircraft Ejection Seat to be Used by Downed Pilots for Environmental Anti Exposure Protection.

摘要

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 under garment 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 250thermal watts to the airman at fluid temperatures of approximately 100to 105 F. The fluid flow rate is approximately .25to .30gallons per minute. The system also has a 12 VDG DC-DC converter used to power an emergency flasher or transmitter.
