Simulation of Full and Part-Load Performance of a Free-Piston Gas Generator by Electronic Analog Methods
Master of Science thesis submitted to the United States Naval Postgraduate School (1960) by Lieutenant Commander Alan F. Barnes. The work uses an electronic analog computer (Boeing Electronic Analog Computer) to simulate the full and part-load performance of a free-piston gas generator (SIGMA GS-34), modeling piston dynamics via Newton's second law with analog circuits representing combustion, compression, bounce-cylinder, and friction forces. Results demonstrate that analog simulation can reproduce free-piston gas generator behavior with reasonable accuracy, validating the method for design and performance prediction of free-piston engine systems.
