ANALYSIS OF A FREE PISTON HYDRAULIC PUMP

Among the sets of attributes investigated in the Concepts-keeping, Evaluation, and Development report, were propulsion system reliability, compactness, efficiency and controllability for the family of on-board propulsion component concepts. The consideration of efficiency and compactness pointed to use of chemical fuel with as high a compression ratio as possible. The resulting free-piston-hydraulic pump, (FPHP) described here is a uniflow scavenged, supercharged diesel engine with potential compression ranges up to or exceeding 50:1. (Author)
