Abstract : Three conditions were investigated for the effect on thermal efficiency and specific air consumption for turbines with an infinite number of stages. The following assumptions were made: the compressor efficiency was 85%, the turbine polytropic efficiency was 88% for both the cooled and uncooled portions of the turbine, the stage efficiency was 85% for a turbine with a finite number of stages. It was concluded that turbines with design inlet temperatures of 2000 deg - 2500 deg F requiring cooling to 1000 deg F can obtain cycle efficiencies within 1 or 2 % of those obtained by turbines requiring cooling to 1500 deg F but designed with inlet temperatures of 2000 deg - 2500 deg F.
