Exergoeconomic analysis of an aircraft turbofan engine
Turgut, Enis Turhan; Karakoç, Tahir Hikmet; Hepbaşlı, Arif (Inderscience Enterprises LTD, 2009)This study deals with an exergoeconomic analysis of an aircraft turbofan engine utilising the kerosene as fuel. A new parameter is developed to define the trust cost rate. The cost of exergy destruction, the relative cost ... -
Exergy analysis of a turbofan aircraft engine
Turgut, Enis Turhan; Karakoç, Tahir Hikmet; Hepbaşlı, Arif; Rosen, Marc A. (Inderscience Enterprises LTD, 2009)An exergy analysis is reported for a General Electric turbofan engine (the CF6-80) using sea-level data. The effects on exergy efficiencies and exergy destructions are investigated of modifying the isentropic efficiencies ... -
Fuel flow analysis for the cruise phase of commercial aircraft on domestic routes
Turgut, Enis Turhan; Cavcar, Mustafa; Usanmaz, Öznur; Canarslanlar, A. Ozan; Döğeroğlu, Tuncay; Armutlu, Kadir; Yay, Ozan Devrim (Elsevier France-Editions Scientifiques Medicales Elsevier, 2014)From the point of view of the environmental impact of aviation, rather than fundamental strategies mainly intended for lower fuel consumption, and thereby less carbon dioxide emissions, more comprehensive approaches have ... -
Investigating actual landing and takeoff operations for time-in-mode, fuel and emissions parameters on domestic routes in Turkey
Turgut, Enis Turhan; Cavcar, Mustafa; Usanmaz, Öznur; Yay, Ozan Devrim; Döğeroğlu, Tuncay; Armutlu, Kadir (Pergamon-Elsevier Science LTD, 2017)Operational landing and takeoff standards developed by the International Civil Aviation Organization (ICAO) in the 1970s, have been widely-used in fuel consumption and emissions models or inventory studies. However, these ... -
A Novel Method to Identify the Nox Emissions of Commercial Aircraft During Descent
Turgut, Enis Turhan (Trans Tech Publications LTD, 2012)In this study a novel method is developed to identify the NOx emissions released from commercial aircraft during descent. In order to obtain EINOx the real flight data and ICAO emissions database are used. According to the ... -
NOx, fuel consumption and time effects of flight path angle during descent
Turgut, Enis Turhan; Usanmaz, Öznur (SAGE Publications LTD, 2013)Due to factors affecting flight operation and air traffic management, such as air traffic separation, avoidance of traffic from congested areas, or facilitating separation with crossing traffic, as well as environmental ... -
Partial substitution of hydrogen for conventional fuel in an aircraft by utilizing unused cargo compartment space
Turgut, Enis Turhan; Rosen, Marc A. (Pergamon-Elsevier Science LTD, 2010)Options are being actively sought in aviation to switch from petroleum-based fuels to alternative fuels, of which hydrogen is a promising candidate, despite challenges associated with its production and storage. The ... -
A Preliminary Study on Relationship between Flight Path Angle and NOx Emissions during Descent
Turgut, Enis Turhan; Usanmaz, Öznur; Kahvecioğlu, Sinem; Rosen, Marc A. (Aidic Servizi Srl, 2014)Interest in the continuous descent approach has recently increased due to opportunities it provides for fuel savings and emissions and noise control. However, the implementation of this procedure involves a number challenges ... -
Relationship between fuel consumption and altitude for commercial aircraft during descent: Preliminary assessment with a genetic algorithm
Turgut, Enis Turhan; Rosen, Marc A. (Elsevier France-Editions Scientifiques Medicales Elsevier, 2012)Despite fuel flow rates being low during descent compared to climb and cruise, the potential exists for significant fuel savings during that phase of flight. Increased fuel use, costs and related environmental impacts are ... -
Wind Effect Analysis on Instrument Flight Procedures Using a Turkish Wind Model
Usanmaz, Öznur; Turgut, Enis Turhan (Amer Inst Aeronaut Astronaut, 2012)This study focuses on an increase in efficiency in the construction of flight procedures considering wind effect in protection areas. In Turkish airspace, the International Civil Aviation Organization wind model is used ...
