Effect of Heat and Power Extraction on Turbojet-Engine Performance. III - Analytical Determination of Effects of Shaft-Power Extraction

Abstract

The performance of an axial-flow-type turbojet engine operating with shaft-power extraction was analytically determined by matching experimentally determined component characteristics of a typical axial-flow-type engine. Performance is presented in the form of generalized working charts that were used to investigate engine performance with variable and rated tail-pipe-nozzle area operation at constant turbine-inlet temperature, constant engine speed, and constant thrust. A range of altitudes and flight Mach numbers was considered. The maximum power extraction permissible is presented as a function of altitude and thrust.
