WebBrayton cycle: gas turbines and jet engines The Brayton cycle is the cycle used in gas turbines and jet engines. It consists of a compressor that increases pressure of the incoming air, then fuel is continuously added to the flow and burned, and the hot exhaust gasses are expanded in a turbine. ... The efficiency depends largely on the ratio of ... WebThe efficiency of the Brayton cycle (1-2-5-6) is given by. η b r a y t o n = 1 − ( 1 r) γ − 1 γ. Here r is the compression ratio, P 2 /P 1, and the process 1-2 is an adiabatic process and for an adiabatic process if the gas is treated as ideal gas then, r = P 2 P 1 = ( T 2 T 1) γ γ − 1 = ( v 1 v 2) γ. The efficiency of the Brayton ...
