Linear Alternator Technologies Used for Free Piston Stirling

Introduction: The NASA Glenn Research Center (GRC) is conducting in-house research on linear alternators (LA’s) to assist in developing free-piston Stirling convertors for radioisotope space power systems. This abstract intends to summarize the existing and potential types of LA’s that may be used with Stirling power convertors. Many of the existing LA types have been tested at NASA GRC and wor...

Free-Piston Diesel Engine Dynamics and Control

Free-piston diesel engines are characterized by freely moving pistons without any rigid crankshaft or camshaft connected to the pistons. This allows a highly compact and e cient engine design, but requires automatic control of the piston motion. This paper present a dynamic mathematical model of a free-piston diesel engine, a control oriented dynamic analysis, and a novel computer-based piston ...
