The simplicity of mechanical design, compactness, light weight, multi fuel capability, and output torque free of cyclic fluctuations are some of the features which should favour the gas turbine engine for most applications. However, the poor thermal efficiency, particularly in the low power range, of the simple gas turbine has prevented its wide spread acceptance. Some improvements in efficiency may be achieved by modifying the basic cycle, but there are a number of aero-thermodynamic factors that tend to limit the minimum power for which a fuel efficient small gas turbine can be designed. The aim of this paper is to examine these factors in some detail. The results of this study should be of interest to the designers of small gas turbine engines.
