Research abstract
SATELLITE-BORNE INFRARED SENSORS PLAY A KEY ROLE IN ANY STRATEGIC DEFENSE ARCHITECTURE. OUR CONCEPT FOR A CRYOGENIC HEAT PIPE DIODE TRANSFERS HEAT FROM A CRYOGENIC FOCAL PLANE ARRAY TO ACTIVE CRYOCOOLERS OR A CRYOGENIC RADIATOR. THE HEAT PIPE DIODE CONTAINS AN INNOVATIVE MICROMACHINED WICK WHICH ENABLES HIGH CAPACITY AND A UNIQUE INTERNAL CONFIGURATION WHICH ENABLES DIODE ACTION. DIODE ACTION ENABLES A REDUNDANT CRYOCOOLER WITHOUT LARGE HEAT LEAK PENALTIES BECAUSE THE CONDUCTIVITY IN REVERSE IS LESS THAN 0.02% OF FORWARD CONDUCTIVITY. THE DIODE'S HIGH FORWARD CONDUCTIVITY REDUCES THE MASS OF A CRYOGENIC COOLING SYSTEM BY 50 KG COMPARED TO A SOLID CONDUCTOR. IN PHASE I WE HAVE DEVELOPED A CONCEPTUAL DESIGN FOR THE HEAT PIPE DIODE AND FABRICATED SAMPLES OF THE MICROMACHINED WICK. IN PHASE II WE WILL FABRICATE AND TEST INDIVIDUAL ELEMENTS OF THE HEAT PIPE AND TEST AN INTEGRATED PROTOTYPE.
