摘要:
In this study, J69 military turbojet aero engine of Cessna T-37B/C pilot trainer aircraft fueled by jet fuel and % 100-biofuel is assessed with aviation, energy, exergy, sustainability, exergoenvironment and thermoeconomic perspectives to show the reliability of the biofuel in terms of various aspects. The methyl-oleate (C19H36O2) is selected as a model substance for biodiesel for this study, because it is similar to the C:H:O ratio of the com-mercial biodiesel. J69 turbojet engine's exergy efficiency increases from 17.058% to 17.103% by using biofuel instead of jet fuel. J69 engine's environmental effect factor rises from 5.261 to 5.299 by the utilization of biofuel. Sustainability index reduces 1.463% for the combustion chamber component, 1.201% for the gas turbine component and 0.735% for the overall J69 engine by using biofuel instead of jet fuel. Fuel cost rates of the jet fuel mode is found as 533.355 $/h, while this cost of the biofuel mode is determined to be 846.058 $/h for take-off operation mode. Thereby, fuel cost of biofuel is higher than jet fuel. Specific exergy cost of jet fuel is determined as 20.14 $/GJ, while it is found as 31.667 $/GJ for biofuel. Results of the biofuel and jet fuel modes are close to each other. Thus, biofuel can be considered as a sustainable aviation fuel for J69 military turbojet engine used on the Cessna T-37B/C pilot trainer aircraft.
