Abstract

This work presents the development of a small-sized Stirling radioisotope generator (SRG) suitable for various applications. It introduces the design, fabrication, and experimental setup of the Stirling engine along with optimization strategies for its operation. Optimization focused on driving frequency, pressure, heater temperature, and piston vibration amplitude to maximize power generation efficiency. The research achieved a maximum power output of 3.05 We with a corresponding generation efficiency of 4.15% under optimized conditions. For the next step of this research, the heat exchange efficiency and motion regularity will be enhanced to improve the generation efficiency exceeding 10%.
