Assessment of emissions at busy airports
Turgut, Enis Turhan; Rosen, Marc A. (John Wiley & Sons LTD, 2010)Emissions are determined in the vicinity of airports and used to demonstrate that aircraft movements in the airport, as measured by landings and takeoffs, are not sufficient to evaluate the cumulative emission formation ... -
Emission assessment of aviation
Turgut, Enis Turhan; Rosen, Marc A. (IGI Global, 2011)Aviation-related emissions and their impacts are comprehensively discussed in this chapter. Previous studies are described in "Previous Studies," and their relevance is discussed throughout the chapter. In "Jet Engine ... -
Emissions at Busy Airports
Turgut, Enis Turhan; Rosen, Marc A. (World Scientific And Engineering Acad And Soc, 2009)Emissions in the vicinity of airports demonstrate that aircraft movements (landings and takeoffs in the airport are not sufficient to evaluate the cumulative emission formation for an airport. Eight busy airports and three ... -
Empirical analysis of the effect of descent flight path angle on primary gaseous emissions of commercial aircraft
Turgut, Enis Turhan; Usanmaz, Öznur; Rosen, Marc A. (Elsevier Sci LTD, 2018)In this study, the effects of descent flight path angle (between 1.25 degrees and 4.25 degrees) on aircraft gaseous emissions (carbon monoxide, total hydrocarbons and nitrogen oxides) are explored using actual flight data ... -
Estimation of vertical and horizontal distribution of takeoff and climb NOx emission for commercial aircraft
Turgut, Enis Turhan; Usanmaz, Öznur; Rosen, Marc A. (Pergamon-Elsevier Science LTD, 2013)An investigation of takeoff and climb NOx emissions is reported for a twin-engine, narrow-body, short-to-medium haul commercial aircraft, B737-800. Ten randomly selected flights are considered for two independent domestic ... -
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 ... -
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 ...
