Advanced radioisotope heat source for Stirling Engines

AIP Conference Proceedings, 2001
The heat exchanger on a Stirling Engine requires a thermal energy transfer from a heat source to the engine through a very limited area on the heater head circumference. Designing an effective means to assure maximum transfer efficiency is challenging.

Mission of Daring: The General-Purpose Heat Source Radioisotope Thermoelectric Generator

4th International Energy Conversion Engineering Conference and Exhibit (IECEC), 2006
The general-purpose heat source radioisotope thermoelectric generator (GPHS-RTG), which was most recently flown on the New Horizons mission to Pluto, was originally conceived in 1979 and executed in a crash program to replace another RTG for the planned International Solar Polar Mission (ISPM). ISPM would later morph into the Ulysses mission to explore

Mixed Americium-Curium Heat Sources for Radioisotope Heaters and Power Systems

Journal of Propulsion and Power, 2011
A blend of americium and curium fuel-cycle discharge products is assessed for its applicability to radioisotope heat-source production for future space and terrestrial radioisotope heat and power systems. Separation techniques such as the selective actinide-extraction process are evaluated and an estimate of the mixed source specific heat output power ...

Quality Assurance Plan for Heat Source/Radioisotope Thermoelectric Generator Programs

1995
The purpose of this document is to serve as the Quality Assurance Plan for Heat Source/Radioisotope Thermoelectric Generator (HS/RTG) programs performed at EG&G Mound Applied Technologies. As such, it identifies and describes the systems and activities in place to support the requirements contained in DOE Order 5700.6C as reflected in MD-10334, Mound ...

Modular Stirling Radioisotope Power System (SRPS) using an advanced heat source

AIP Conference Proceedings, 2001
The advanced Stirling engine/alternator developed by Stirling Technology Company has potential for a wide range of space applications, at an efficiency comparable to solar cells and triple that of thermoelectric elements. However, the unique design of the Stirling engine requires a concentrated heat input in an annular band which would be optimized ...

Design, development and testing of 60-watt radioisotope heat source strength member

AIP Conference Proceedings, 1995
To satisfy the safety requirements of a terrestrial 60‐Watt Radioisotope Heat Source, it was necessary to determine whether the internal pressure buildup from the helium generated from Pu‐238 decay would pose problems in a fire environment (time/temperature/internal pressure).

[Blood heat exchangers for the artificial heart using a radioisotope power source].

Meditsinskaia tekhnika, 1979
A design of a vascular heat exchanger enabling it to establish in experiments with animals the degree of the possible specific-capacity thermal loads has been devised. The performance results may be taken account of in designing implantable appliances of assistive circulation and artificial heart.
