Comparison of Some Turboprop Cycles for Subsonic Speeds 510193

AN ANALYSIS has been made of the performance of basic, reheat, regenerative, and regenerative-plus-reheat turboprop engines for flight speeds of 200-600 mph, altitudes of 0-50,000 ft, and turbine inlet temperatures of 2000-2500 R, and a range of compressor pressure ratios of 6-42.
The effects of flight and engine design conditions on fuel consumption, power per unit engine frontal area, power per pound of engine weight, and airplane range are compared for several types of turboprop engine.
