METHOD FOR DETERMINING OPTIMUM DIVISION OF POWER BETWEEN JET AND PROPELLER FOR MAXIMUM THRUST POWER OF A TURBINE-PROPELLER ENGINE

摘要

Charts are presented by which the Jet pressure ratio that gives optimum division of power between propeller and jet for maximum total thrust power may be conveniently determined for any turbine-propeller engine with or without interfolding, reheat, regeneration, or any combination of these modifications. Performance curves for various engine cycles show that the Jet pressure ratio that pro¬duces maximum total power output also gives minimum or very nearly minimum specific fuel consumption.
