Unformatted text preview: stand. This limits the pressure ratios that can be used For fixed values of Tmin and Tmax, the net work first increases with the pressure ratio, then reaches a maximum and finally decreases Brayton Cycle Brayton The two major application areas of gas-turbine engines are aircraft propulsion and electric power generation The air in gas turbines supplies the necessary oxidant for the combustion of the fuel, and it serves as a coolant to keep the temperature of various components within safe limits. An air– fuel ratio of 50 or above is not uncommon Brayton Cycle Brayton The fraction of the turbine work used to drive the compressor is called the back work ratio In gas turbine more than half of the turbine work drives the compressor. This is...
