  4. Abstract:
  5. In this paper, the effect of turbine stage efficiency on fuel consumption of both gas turbines and aerial engines is assessed quantitatively. At the beginning of the gas generator optimization to decrease the fuel consumption, it is necessary to analyze the sensitivity of fuel consumption to its main components efficiencies. This will guide us which component is more important to be optimized. Here a zero-dimensional analysis has been done to determine the effect of turbine stage efficiency on the fuel consumption. Results of this analysis are evaluated in the context of thermodynamic cycle of a gas turbine generator and an aerial engine. As an example, it is shown that if the efficiency of first stage of the turbine is increased from 82% to 84%, the fuel consumption of an aerial engine is computed to be decreased by 1%. The cycle analysis performed implies that the sensitivity of fuel consumption to turbine stage efficiency varies for different values of stage efficiency. Copyright
