The manual defines the Stirling engine as a closed-cycle regenerative heat engine that converts external heat into mechanical work. Unlike internal combustion engines, its working fluid (such as air, helium, or hydrogen) is never exhausted, leading to exceptionally quiet and low-vibration operation.
The design process revolves around four key thermodynamic stages: Building a Stirling Engine: A STEM Education Program Stirling Engine Design Manual
The , authored by William R. Martini and originally prepared for NASA and the U.S. Department of Energy, serves as a cornerstone for both novice enthusiasts and professional engineers. It organizes the complex literature of Stirling cycle heat engines into an accessible guide for modeling, evaluating, and optimizing hardware.
