gas turbine uses low air-fuel ratio to economise on fuel

gas turhine uses high air-fuel ratio to reduce outgoing temperature

gas turbine uses low air-fuel ratio to develop the high thrust required

all of the above

increase in net output but decrease in thermal efficiency

increase in thermal efficiency but decrease in net output

increase in both thermal efficiency and net output

decrease in both thermal efficiency and net output

large gas turbines employ axial flow compressors

axial flow compressors are more stable than centrifugal type compressors but not as efficient

axial flow compressors have high capacity and efficiency

axial flow compressors have instability region of operation
