May 24, 2017National Aeronautics and Space AdministrationNASA SHARED SERVICES CENTERNNX17CJ23P541712IGF::OT::IGF NASA HAS IDENTIFIED A NEED FOR HIGHER HEAT REJECTION TEMPERATURES DUE TO AN EQUATORIAL LUNAR MISSION PROFILE, WHERE SURFACE TEMPERATURES REACH 400 K. TO MEET THIS NEED FOR SPACE EXPLORATION VEHICLES TO REJECT WASTE HEAT TO HIGH TEMPERATURE HEAT SINKS, MAINSTREAM PROPOSES ADAPTING OUR OIL-LESS VAPOR-COMPRESSION (V-C) REFRIGERATION COMPRESSOR TECHNOLOGY FOR OPERATION AT HIGH TEMPERATURE AND HIGH LIFT. VAPOR-COMPRESSION SYSTEMS USE TWO-PHASE HEAT TRANSFER WHICH REDUCES COMPONENT SIZE AND MASS OVER SINGLE-PHASE HEAT PUMPING CYCLES SUCH AS REVERSE-BRAYTON OR STIRLING. MAINSTREAM?S CURRENT OIL-LESS V-C COMPRESSOR TECHNOLOGY IS GRAVITY-INSENSITIVE, HAS A LONG OPERATING LIFE, CAN BE SCALED TO MATCH VARIOUS HEAT LOADS, AND HAS BEEN MISSION-PROVEN ON THE INTERNATIONAL SPACE STATION (ISS) PLACING IT AT A TRL 9. THE PROPOSED DEVELOPMENT EFFORT WILL EXTEND THIS COMPRESSOR TECHNOLOGY TO OPERATION AT HIGH TEMPERATURES AND HIGH LIFT, TO WHICH IT IS INHERENTLY WELL-SUITED. THE RESULTING COMPRESSOR WILL BE AN ENABLING TECHNOLOGY FOR THE NEEDED HIGH TEMPERATURE HEAT PUMPING SYSTEMS.$125K

Apr 23, 2017National Aeronautics and Space AdministrationNASA SHARED SERVICES CENTERNNX17CP03C541712IGF::OT::IGF A BIDIRECTIONAL DUAL ACTIVE BRIDGE (DAB) DC-DC CONVERTER FOR ELECTRICAL POWER SYSTEMS (EPS) IS PROPOSED. THE CONVERTER OPERATES AS A CHARGER, UP CONVERTER, AND DOWNCONVERTER USING A SINGLE TRANSFORMER. THE CONVERTER USES SMART TECHNOLOGY TO INTERLEAVE DAB CONVERTER STAGES FOR RIPPLE CURRENT REDUCTION AND OPTIMIZED LOAD SHARING OF STAGES TO EXTEND THE HIGH EFFICIENCY LOAD RANGE OF THE CONVERTER TO 6.25% OF FULL LOAD. BY USING SMART TECHNOLOGY, THE LOAD CONDITION OF EACH DAB CONVERTER STAGE IS MONITORED AND ITS LOAD SHARING CONTROLLED DEPENDING ON THE CONVERTERS TOTAL LOAD CONDITION. IN THIS WAY, EACH CONVERTER STAGE IS KEPT AT OR ABOVE 25% LOAD. THEREFORE THE MINIMUM LOAD OF THE NEW DAB CONVERTER WITH FOUR INTERLEAVED STAGES IS ONE FOURTH OF 25% OR 6.25%. THE DESIGN EMPLOYS RADIATION-RESISTANT AND CRYOGENIC-TEMPERATURE-CAPABLE GAN HEMT DEVICES TO PROCESS 2 KW OF POWER PER STAGE. MAINSTREAM HAS TESTED GAN HEMT DEVICES TO -225 C. GS66508T GAN HEMT DEVICES ARE RATED FOR 650 VDC MAXIMUM DRAIN-TO-SOURCE MAXIMUM VOLTAGE STRESS ALLOWING FOR A MAXIMUM STEADY-OPERATING VOLTAGE OF 400 VDC AT 60% DERATING.$754K

Jun 13, 2016National Aeronautics and Space AdministrationNASA SHARED SERVICES CENTERNNX16CJ13C541712IGF::OT::IGF THE EFFICIENT THERMAL CONTROL OF VEHICLES IS ESSENTIAL TO THE SUCCESS OF EVERY SINGLE NASA MISSION. ALL VEHICLES HAVE VERY TIGHT REQUIREMENTS FOR THE THERMAL CONTROL SYSTEMS WHILE SIMULTANEOUSLY PLACING INCREDIBLY STRINGENT DEMANDS UPON THEM. THESE DEMANDS ARE GETTING EVEN MORE INTENSE GIVEN THE SHIFT TOWARDS VARIABLE HEAT REJECTION, WHICH IS ESSENTIAL IN MISSIONS REACHING BEYOND THE LOWER EARTH ORBIT. SPECIFICALLY, THE THERMAL CONTROL FLUID MUST MAINTAIN EXCELLENT THERMAL PROPERTIES FOR HEAT REJECTION UNDER PEAK CONDITIONS WHILE AT THE SAME TIME REMAIN LIQUID AT EXTREMELY LOW TEMPERATURES. CURRENTLY USED FLUIDS EITHER DO NOT MEET THE LOW TEMPERATURE REQUIREMENT (GLYCOL/WATER MIXTURE) OR DO NOT HAVE THERMAL PROPERTIES CONDUCIVE TO A COMPACT, EFFICIENT SYSTEM (GALDEN). MAINSTREAM HAS IDENTIFIED SEVERAL PROMISING NEXT GENERATION THERMAL FLUIDS USING COMPUTATION CHEMICAL TECHNIQUES. MAINSTREAM HAS ALREADY DEMONSTRATED IN PHASE I THAT THESE FLUIDS ARE SUPERIOR TO INCUMBENT FLUIDS. IN PHASE II, MAINSTREAM WILL PERFORM MORE LONG TERM DURABILITY, COMPATIBILITY AND PERFORMANCE STUDIES IN A SIMULATED TEST-LOOP REPRESENTATIVE OF CONDITIONS ENCOUNTERED ON NASA SPACECRAFT.$749K
