Abstract : This document presents the methods and procedures used and the results obtained in the design, fabrication, and testing of a rotary vane type compressor operated on air cycle thermodynamics. The history and results of the testing of a similar expander are summarized and the full report of that work is referenced. The machine design used was based on one patented by Ecton Corporation. The goal of the reported effort was to demonstrate the attainable efficiencies of these machines. Appropriate test rigs were assembled and the machines were tested at various operating conditions. The compressor testing did not achieve the full design speed because of time constraints but important data was obtained at 87% speed (3000 rpm). The maximum measured total efficiencies were 78% for the expander and 71% for the compressor. Various design improvements which may yield improved performance were identified and reported.
