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

less

more

same

may be less or more depending on ambient conditons

large gas turbines use radial inflow turbines

gas turbines have their blades similar to steam turbine

gas .turbine′s blade will appear as impulse section at the hub and as a reaction section at tip

gas turbines use both air and liquid cooling
