THE OBJECT OF THE PROPOSED STUDY IS TO CONDUCT AN EVALUATION OF THE FEASIBILITY AND PREDICTED PERFORMANCE OF A CLASS OF PULSED SPACE POWER SYSTEMS CHARACTERIZED BY THE USE OF (A) INTER-PULSE ENERGY STORATE IN FLYWHEELS, (B) THERMAL STORAGE FOR INTERMEDIATE TIMES (1 HOUR), (C) A SOLAR DRIVEN CLOSED BRAYTON CYCLE WITH CERAMIC COMPONENTS AND HIGH PEAK TEMPERATURE. NUCLIAR SOURCES COULD BE SUBSTITUTED FOR THE SOLAR HEATER. THIS TYPE OF SYSTEM IS OF INTEREST FOR SPACE-BASED LASERS AND FOR CERTAIN ELECTRIC PROPULSION APPLICATIONS. PRELIMINARY ESTIMATES INDICATE A STRONG POTENTIAL FOR LIGHTWEIGHT, LONG LIFE AND OPERATIONAL FLEXIBILITY. THE STUDY WOULD CONSIST OF A COMBINATION OF SYSTEM OPTIMIZATION AND CRITICAL COMPONENT EVALUATION STUDIES.
