Aero-propulsive modelling for climb and descent trajectory prediction of transport aircraft using genetic algorithms
Baklacıoğlu, Tolga; Cavcar, Mustafa (Royal Aeronautical Society, 2014)In this study, a new aero-propulsive model (APM) was derived from the flight manual data of a transport aircraft using Genetic Algorithms (GAs) to perform accurate trajectory predictions. This new GA-based APM provided ... -

Analysis of Test-Cell Emission Measurements of Newly Overhauled Turbofan Engines
Turgut, Enis Turhan; Cavcar, Mustafa; Yay, Ozan Devrim; Ucarsu, Mehmet; Yılmaz, Elif; Usanmaz, Öznur; Miake-Lye, Richard C. (Amer Inst Aeronautics Astronautics, 2015)In this study, the gaseous emissions of newly overhauled CFM56-3B1 and -3B2 series turbofan engines are measured in a test-cell environment during typical functional and performance test procedures. The measured emissions ... -
Approximate solutions of range for constant altitude - constant high subsonic speed flight of transport aircraft
Cavcar, Aydan; Cavcar, Mustafa (Editions Scientifiques Medicales Elsevier, 2004)Approximate cruise range solutions are introduced for the constant altitude - constant high subsonic speed flight of turbojet/fan transport aircraft with cambered wing design. The variation of the specific fuel consumption ... -
Design, flight mechanics and flight demonstration of a tiltable propeller VTOL UAV
Öznalbant, Zafer; Kavsaoğlu, Mehmet Şerif; Cavcar, Mustafa (American Institute of Aeronautics and Astronautics Inc, AIAA, 2016)This paper presents the design, flight mechanics and flight demonstration studies of a novel tiltable propeller VTOL UAV. The aircraft, discussed in this study, consists of a forward-swept fixed wing, two pairs of counter ... -
The effect of flight distance on fuel mileage and CO2 per passenger kilometer
Turgut, Enis Turhan; Usanmaz, Öznur; Cavcar, Mustafa (Taylor & Francis Inc, 2019)In this study, the effect of distance on fuel mileage (fuel burn per nautical mile) and CO2 intensity, based on a large amount of actual flight data, is discussed for narrow-body commercial aircraft performing domestic ... -
Estimating gaseous emissions production of an entire flight of a commercial aircraft based on emission measurements and actual flight data records
Turgut, Enis Turhan; Cavcar, Mustafa; Yay, Ozan Devrim; Ucarsu, Mehmet; Yılmaz, Elif; Usanmaz, O.; Döğeroğlu, Tuncay (Deutschen Forschungsanstalt fur Luft-und Raumfahrt, 2015)In this study, engine emissions measurement results and actual flight data records are used to obtain an emissions production profile of gate-To-gate flight activity. The platform and pow- erplant selected arc B737-800 and ... -
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 ... -
Impact of aircraft performance differences on fuel consumption of aircraft in air traffic management environment
Cavcar, Aydan; Cavcar, Mustafa (Emerald Group Publishing Limited, 2004)Performance differences between the aircraft types are natural and they inevitably cause problems in the air traffic system, particularly when slower aircraft types are followed by faster types in a climb or cruise queue. ... -
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 ...
