Our project is Stirling Engines for Space Applications aims to develop a comprehensive MATLAB-based model of a Stirling engine using Simscape. The objective is to enable high-level analysis of Stirling engines for potential use in space missions, particularly for the Psyche asteroid mission. The Stirling cycle, which involves cyclic compression and expansion of gas with an external heat source, offers advantages like high efficiency and reliability for extended space missions. The project involves extensive research on Stirling engine operation, the creation of a 3D model, and the implementation of non-idealities to optimize the engine. The model emphasizes analysis, optimization, and operational understanding, with potential educational uses as well.
