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
The two major application areas of gas-turbine
engines are aircraft propulsion and electric power
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
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...
