An aircraft gas turbine operates on a Brayton cycle with a pressure ratio of 12. Due to aerodynamic losses, the compressor has an isentropic efficiency of 85% and the turbine has an isentropic efficiency of 90%. If the compressor inlet conditions are 250 K and 80 kPa, and the turbine inlet temperature is 1300 K, what is the actual thermal efficiency of this cycle?
