Scientific paper
A design study was conducted to characterize conceptual designs for a small Radioisotope Thermoelectric Generator (RTG), one that might be suitable for future planetary missions. Conceptual design configurations were derived from the General Purpose Heat Source-RTG (GPHS-RTG), with the design goal of providing 70 watts of electrical power at the end of a ten year mission life. Design improvements for mass minimization were evaluated, considering also the technical risk of the corresponding engineering development required. It was concluded that an RTG mass of 18 kg could be achieved with moderate risk. Further studies are recommended to define in detail the testing and other development activities that would be required to bring the conceptual design for such an RTG to reality.
