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 ... -
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 ... -
Estimating Aircraft Fuel Flow for a Three-Degree Flight-Path-Angle Descent
Turgut, Enis Turhan (Amer Inst Aeronaut Astronaut, 2011)The objective of this study is to develop statistically significant models in order to determine the effects of altitude on fuel consumption of commercial aircraft during descent for a specific flight-path angle. In this ... -
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 ... -
Exergetic analysis of an aircraft turbofan engine
Turgut, Enis Turhan; Karakoç, Tahir Hikmet; Hepbaşlı, Arif (John Wiley & Sons LTD, 2007)The main objective of the present study is to perform an exergy analysis of a turbofan kerosene-fired engine with afterburner (AB) at sea level and an altitude of 11000 m. The main components of this engine include a fan, ... -
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 ... -
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 ...
