Formatted abstract
The world shortage of radioisotope plutonium-238 is a cause for concern regarding potential future space missions. With limited stock remaining, there is demand for more efficient  systems to better utilise the remaining fuel. One such system currently still in development is the  Advanced Stirling Radioisotope Generator utilising Stirling technology that is expected to  quadruple the efficiency of current radioisotope power systems.

This project has put forward a potential CubeSat Stirling Radioisotope Generator (CSRG) designed to  be launched as a CubeSat payload allowing for easier access to space for easier acquisition of  space heritage for Stirling technology. It’s initial theoretical efficiency is then analysed using  the isothermal, adiabatic, and simple analyses. Although successful, due to the constraints imposed  by the CubeSat design requirements, namely the limited working pressure, the calculated efficiency
is limited to 2.4%.

Overall, the primary objectives of providing a CubeSat based Stirling generator design and applying  an analysis of its efficiency were successful and further recommendation were made pertaining to its future development.
