Stirling Engine


For ReGen Power Systems

After some starts and stops, and two company name changes, ReGen Power Systems (RGPS) secured funding to build a scaled version of its own, unique version of a traditional Stirling Engine that promised to be more efficient and cost less than any comparable prime mover in its class. This confidential, patent pending technology required the DBA team to bring to bear a wide range of innovative technology in order to meet some difficult design constraints. New approaches to sealing gas, fabricating high temperature, tight tolerance, low clearance, quick acting, low friction valves and balancing mass flows, gas volumes and addressing thermal issues posed some daunting challenges. By doing detailed multi-physics systems analysis up front, combined with component level structural, stress, vibration, thermal and fluids analysis a detailed engine design emerged. DBA assisted in procuring and fabricating many of the engine parts.
