IGF::OT::IGF THE GOAL OF THE PROPOSED EFFORT IS TO USE SELECTIVE LASER MELTING (SLM, AN ADDITIVE MANUFACTURING TECHNIQUE) TO MANUFACTURE A HOT FIRE-CAPABLE, WATERCOOLED SPOOL PIECE THAT FEATURES AN ADVANCED REGENERATIVE COOLING TECHNIQUE THAT COMBINES HIGH HEAT FLUX PERFORMANCE WITH LOW PRESSURE DROP. SLM ENABLES US TO "PRINT" THE SPOOL PIECE IN DAYS, DESPITE THE COMPLEXITY OF THE REGENERATIVE LINER'S INHERENT FLOW PASSAGE COMPLEXITY. THIS REDUCTION IN MANUFACTURING LEAD TIME, COMBINED WITH THE FACT THAT SLM MANUFACTURING COSTS ARE DRIVEN IN LARGE PART BY THE AMOUNT OF RAW POWDER USED DURING FABRICATION, RESULTS IN A SUBSTANTIAL COST REDUCTION FOR FUTURE REGENERATIVELYCOOLED ROCKET ENGINES. ADDITIONALLY, THE PROPOSED ADVANCED REGENERATIVE COOLING APPROACH FEATURES A HEAT-PICKUP EFFICIENCY THAT IS AT LEAST TWO ORDERS OF MAGNITUDE HIGHER THAN TRADITIONAL MILLED CHANNEL LINERS AND/OR BRAZED TUBE BUNDLE CHAMBERS. AS A RESULT OF OUR PHASE I ACTIVITY AND CONFIDENCE IN OUR COMMERCIALIZATION PATH, WE WILL BE MAKING A CAPITAL INVESTMENT TO STAND UP AN SLM MANUFACTURING CAPABILITY IN HOUSE. WE PLAN TO AUGMENT THAT INVESTMENT WITH AN INTERNALLY-FUNDED TRADE STUDY THAT WE WILL USE TO DERIVE MAIN COMBUSTION CHAMBER PERFORMANCE REQUIREMENTS FOR A FUTURE EXPANDER CYCLE ENGINE. THOSE REQUIREMENTS WILL FEED INTO PHASE II DESIGN REQUIREMENTS AND, ULTIMATELY, TO SUPPORTING OUR COMMERCIALIZATION OPPORTUNITY PRESENTED BY THE AFFORDABLE UPPER STAGE ENGINE PROGRAM.

IGF::OT::IGF WE OFFER AN ULTRA-COMPACT KLYSTRON AMPLIFIER FOR REMOTE SENSING ON CUBESATS. IT WILL OPERATE AT 35.7 GHZ, HAVE 400 MHZ BANDWIDTH, AND OUTPUT GREATER THAN 32 WATTS WITH 35 DB GAIN. IT EMPLOYS A TWO-STAGE DEPRESSED COLLECTOR, ALLOWING PRIME EFFICIENCY OF 50%. COMPARABLE SOLID STATE POWER AMPLIFIERS HAVE 15% EFFICIENCY AND OUTPUT ONLY 7 W. KLYSTRONS ARE THE ONLY AMPLIFIER TECHNOLOGY THAT CAN BE MINIATURIZED TO THIS DEGREE. VOLUME WITH POWER CONDITIONER AND DRIVER IS LESS THAN 0.500 CM3, HALF THE ALLOWED SPACE. IT USES A BREAKTHROUGH ULTRAMINIATURE SCANDATE CATHODE CAPABLE OF 100A/CM2 AT 1000 DEGREES C AND 5A/CM2 AT LESS THAN 800 DEGREES C. AT THIS TEMPERATURE, LIFE IS MORE THAN 100,000 HOURS. THE KLYSTRON USES CATHODE RAY TUBE CONSTRUCTION, WHICH LOWERS WEIGHT, SIZE AND COST (TWO TO FIVE TIMES LESS THAN STANDARD BRAZED CERAMIC-METAL CONSTRUCTION). PARTS ARE FASTENED VIA GLASS RODS OR MECHANICAL CAPTURE OR BY SPOT WELDING. MOST PARTS ARE STANDARD OFF-THE-SHELF, WHICH FURTHER LOWERS COST. IT USES A GLASS VACUUM ENVELOPE, GLASS FEEDTHROUGHS, COMBINATION RF WINDOWCOUPLER AND BARIUM GETTERS TO MAINTAIN VACUUM. IN PHASE I WE SUCCESSFULLY BUILT TWO BEAM TESTERS. IN PHASE II WE CONSTRUCT AN ENTIRE AMPLIFIER PACKAGE IN CUBESAT VOLUME. E BEAM, INC. IS A LEADER IN INNOVATIVE MINIATURE CATHODES, ELECTRON GUNS AND VACUUM ELECTRON DEVICES GENERALLY. IT HAS LONG PROMOTED CATHODE RAY TUBE CONSTRUCTION AS A WAY TO MASS PRODUCE MEDIUM POWER MICROWAVE TUBES.

HIGH EFFICIENCY, HIGH TEMPERATURE FOAM CORE HEAT EXCHANGER FOR FISSION SURFACE POWER SYSTEMS, PHASE II FISSION-BASED POWER SYSTEMS WITH POWER LEVELS OF 30 TO 100 KWE WILL BE NEEDED FOR PLANETARY SURFACE BASES. DEVELOPMENT OF HIGH TEMPERATURE, HIGH EFFICIENCY HEAT EXCHANGERS IS CRITICAL FOR NEXT-GENERATION NUCLEAR POWER AND SPACE PROPULSION SYSTEMS. IN PHASE I, ULTRAMET AND SANDIA NATIONAL LABORATORIES DEMONSTRATED THE FEASIBILITY OF USING HIGH SURFACE AREA FOAM CORE HEAT EXCHANGER TECHNOLOGY TO SUBSTANTIALLY IMPROVE THE POWER CONVERSION EFFICIENCY OF LIQUID METAL-TO-GAS HIGH TEMPERATURE HEAT EXCHANGERS FOR FISSION SURFACE POWER SYSTEMS. PRELIMINARY DESIGN AND MODELING SUGGESTED A SUBSTANTIAL IMPROVEMENT IN THE EFFICIENCY OF A LIQUID LITHIUM-TO-HELIUM COMPONENT RELATIVE TO CONVENTIONAL PLATE-FIN HEAT EXCHANGERS, AND HARDWARE FABRICATION AND TESTING DEMONSTRATED THE MANUFACTURABILITY, PERFORMANCE, AND SIMPLICITY OF THE FOAM-BASED DESIGN. OPEN-CELL FOAM IS A NATURAL COOLANT CHANNEL THAT DOES NOT REQUIRE EXTENSIVE, EXPENSIVE MACHINING OF INTRICATE COOLANT PASSAGES AND ELIMINATES THE NEED FOR BRAZE-BONDING OR WELDING OF NUMEROUS INDIVIDUAL SECTIONS. INITIAL TESTING SHOWED THE ABILITY OF TEXTURED, VAPOR-DEPOSITED LITHIUM-COMPATIBLE COATINGS TO BE UNIFORMLY WETTED BY LIQUID LITHIUM AT LOW TEMPERATURE. THE TECHNOLOGY HAS THE POTENTIAL TO BEST MINIMIZE THE TEMPERATURE DIFFERENCE BETWEEN THE MAXIMUM LITHIUM REACTOR COOLANT AND HELIUM WORKING FLUID TEMPERATURES, AS WELL AS TO REDUCE SYSTEM MASS AND VOLUME THROUGH THE USE OF HIGH SURFACE AREA, LOW DENSITY OPEN-CELL FOAM, AND INCREASE SAFETY AND RELIABILITY BY MINIMIZING THE NUMBER OF PIECE PARTS AND ASSOCIATED JOINTS. IN PHASE II, ULTRAMET WILL TEAM WITH SANDIA TO EXPAND ON THE PHASE I SUCCESS BY PERFORMING COMPREHENSIVE DESIGN AND STRESS ANALYSIS, DETERMINING PHYSICAL PROPERTIES, AND ESTABLISHING PERFORMANCE THROUGH HIGH TEMPERATURE (1000 K) THERMAL RESPONSE AND FLOW TESTING OF COAXIAL HEAT EXCHANGERS USING THE HELIUM FLOW LOOP AND LIQUID METAL INTEGRATED TEST SYSTEM AT SANDIA'S PLASMA MATERIALS TEST FACILITY.
