Assessment of Thermodynamics Performance for Prop Engine Based on Temperature Effect of Flight Altitude

In recent years, significant gains have been made in aircraft engine technologies, which have increased their sectoral potential. However, irreversibility based on fossil fuel consumption has an important environmental pollutant role. For engines, the fuel consumption combined with the emission management-related altitude conditions is an important input to evaluate the potential. Generally, three different altitude definitions are valid for airplanes in engine performance measures. In particular, flight altitude is an important input for decision processes and this is valid for 9000 ft in sectoral structure. First law and second law analyses were developed for the defined boundary temperature values of the flight altitude for the prop engine referenced in this study. Then, the entropy potential of the temperature effect at the boundary conditions for the altitude conditions was evaluated, and the environmental effect was evaluated. At the end of the study, evaluations of entropy management were made for performance effects.
