Gas Turbine Improvements

• Increase the gas combustion temperature (T3) before it enters the turbine since hth = 1 - (T4/T3)
  • Limited by metallurgical restriction: ceramic coating over the turbine blades
  • Improved intercooling technology: blow cool air over the surface of the blades (film cooling), steam cooling inside the blades.
    

• Modifications to the basic thermodynamic cycle: intercooling, reheating, regeneration

• Improve design of turbomachinery components: multi-stage compressor and turbine configuration. Better aerodynamic design on blades (reduce stall).
