A simplified analysis is applied to a gas turbine engine cycle that has a compression ratio of 8 to 1. The compressor and turbine inlet temperatures are, respectively, 300 K and 1400 K. Values of gas (air) properties are obtained from the Air-gas tables. The compressor and turbine machine efficiencies are, respectively, 0.85 and 0.90. The gas-to-air mass ratio is 1.02 to 1. Calculate the thermal efficiency for the cycle and the thermal efficiency for the corresponding air standard Brayton cycle.
