Adequate electrical power for spacecraft operations is a crucial mission task. the isotope heat sources used in radio-isotope-thermoelectric-generators for many nasa missions are expensive. for a given electrical power, thermal-to-electric conversion with amtec rather than conventional… More

As an alternative to holographic laser radar, AMPS will develop a 3-D imaging concept that collects far-field intensity speckle patterns. This kind of measurement greatly relaxes the tolerances on vibration and coherence length. However, phase retrieval will be required to retrieve a 3-D image.… More

A key component in the Alkali Metal Thermal to Electric Converter (AMTEC) is the electrode that is generally sputter deposited on the beta"-alumina solid electrolyte (BASE). Electrode deposition, as it is now practiced however, is a random process that covers active sites on the BASE and places many… More

THE ALKAI METAL THERMAL OF ELECTRIC CONVERTER (AMTEC) IS A STATIC ENERGY CONVERSION DEVICE THAT OPERATES AT THERMAL TO ELECTRIC CONVERSION EFFICIENCIES THAT ARE INDEPENDENT OF SIZE, HAVE REACHED 19% AND ARE EXPECTED TO REACH 25% TO 30% IN EARLY 1995. THESE SYSTEMS OPERATE SILENTLY, WITH NO MOVING… More

The small spacecraft power system proposed in this program provides significant advantages over state-of-the-art systems including: (1) use of a high efficiency (25%-35%) AMTEC, static power conversion system, (2) reduced planform area, and vulnerability, (3) mass efficient phase change material for… More

The Alkali Metal Thermal to Electric Converter (AMTEC) technology is ideal for auxiliary electric power supplies (AEPS) that must operate over a broad range of temperatures, fuel sources, power levels, and operational specifications. The simplicity, efficiency and modularity, as well as the high… More

Alkali Metal Thermal to Electric Converters (AMTEC) convert heat to electricity at high efficiency without moving parts at temperatures compatible with current solar receiver technology. A Phase I program is proposed which will deliver an integrated, high-temperature thermal storage/high-efficiency… More

Improvements in channel capacity (i.e. bit rate) of mobile communication systems are important for extending their range and data throughput capabilities for current military and civilian applications and enable a number of new, highly marketable,applications. The objective of the program is the… More
