WebbPressure ratio is the ratio of the compressor discharge pressure and the inlet air pressure. Aeroderivative engines are derived from jet engines, as the name implies, and operate at very high compression ratios (typically in excess of 30). Aeroderivative engines tend to be very compact and are useful where smaller power outputs are needed. WebbHowever, there are practical limitations in increasing the pressure ratio. First, as you increase the pressure ratio, it increases the compressor exhaust temperature. This can result in the temperature of the gas leaving the combustion chamber exceeding the metallurgical limits of the turbine.
