    Comparative Analysis of Using Diesel/Jp-8 Fuel Blends and Jp-8 for the Exergetic Sustainability Performance of an Uav Turbojet Engine
    (Inderscience Enterprises Ltd, 2023) Yücer, Cem Tahsin; Nacaklı, Yavuz
    In this study, it is aimed to analyse the effects for the partial use of diesel fuel with kerosene-based JP-8 on the jet engine's performance by using exergetic sustainability parameters. Three fuel types were defined as 100% JP-8, 75% JP-8/ 25% Diesel and 50% JP-8/ 50% Diesel. Firstly, the exergy analysis was implemented to the jet engine components. Then five exergetic sustainability parameters: waste exergy ratio (WER), environmental effect factor (EEF), exergetic sustainability index (ESI), ecological effect factor (EcoEF) and sustainability efficiency factor (SEF) were calculated. The exergetic sustainability parameters showed that the increase in diesel fuel use caused slightly higher WER, EEF and EcoEF values, as well as slightly lower ESI and SEF values for the combustion chamber and overall jet engine. It was concluded that partial use of diesel can be an alternative for low altitudes under obligatory conditions in small UAV turbojet engines.

    Effects of Using Hydrogen on the Exergetic and Environmental Damage Performance of an Uav Turbojet Engine
    (Sage Publications Ltd, 2023) Yücer, Cem Tahsin; Nacaklı, Yavuz
    In this study, the performance effects of using hydrogen instead of JP-8 fuel in an unmanned aerial vehicle (UAV) jet engine was investigated. Exergy analysis and environmental damage analysis were used to obtain performance parameters. These performance parameters were exergy destruction ratio, thrust-specific fuel consumption, air-to-fuel ratio, exergy efficiency, waste exergy ratio, environmental effect factor, sustainability index, and exergetic improvement potential values. Turbojet engine was operated at three different throttle settings (50%, 75%, and 100%) to examine the impact of different load types on the performance parameters. The results obtained by using JP-8 and hydrogen fuels at different throttle settings showed consistency. For all throttle settings, the highest exergy efficiencies took place in the nozzle as approximately 90%. On the other hand, the combustion chamber had the lowest exergy efficiencies for all conditions and took values between 30% and 40%. Calculated exergy destruction ratios indicated that the hydrogen use improved or saved the jet engine's energy performance. Except the combustion chamber, compressor, turbine, and nozzle exergy destruction ratios decreased as 6.2%, 6.5%, and 10.8%, respectively. Moreover, the use of hydrogen fuel did not significantly change the performance parameters, in fact reduced the environmental impact approximately 113%. The findings indicated the potential benefits of hydrogen fuel use when compared to JP-8 fuel.

    Effects of the Partial Use of Diesel Fuel With Kerosene on the Exergetic Sustainability Performance of a Uav Jet Engine in Case of Emergency
    (Springer Nature, 2024) Yucer, C.T.; Nacakli, Y.
    This study aims to analyze the effects of using diesel fuel partially with kerosene on the jet engine’s performance by using exergetic sustainability parameters in obligatory cases where there is no or limited access to JP-8 fuel. Low altitude use will also overcome the negative effects of diesel use at low temperatures. To this extent, firstly, the exergy analysis was implemented on the jet engine components. Exergy flows were determined as fuel and product for each component: compressor, combustion chamber, gas turbine, and nozzle. Exergy destructions for each component were obtained. The calculated exergy destructions were one of the key figures to understand the improvement potentials of the jet engine components. Then four exergetic sustainability parameters: exergy efficiency (EE), waste exergy ratio (WER), environmental effect factor (EEF), and exergetic sustainability index (ESI), were studied. According to the findings, it was concluded that partial use of diesel can be an alternative for low altitudes in small UAV turbojet engines in case of emergencies. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.
