Experimental studies of particle packing and combustion behavior of the slip cast SiO2-Al-C system
(Kluwer Academic Publ, 2000)… -
Approximate solutions of range for constant altitude - constant high subsonic speed flight of transport aircraft
(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 ... -
Impact of aircraft performance differences on fuel consumption of aircraft in air traffic management environment
(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. ... -
Constant altitude-constant Mach number cruise range of transport aircraft with compressibility effects
(Amer Inst Aeronaut Astronaut, 2006)An approximate solution of the constant altitude-constant Mach number cruise range for high subsonic speed flight of the turbojet/fan aircraft is proposed. The solution considers cambered wing drag polar of modern transport ... -
Exergetic analysis of an aircraft turbofan engine
(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, ... -
A knowledge-based conflict resolution tool for en-route air traffic controllers
(Emerald Group Publishing LTD, 2008)Purpose - The purpose of this paper is to develop a knowledge-based decision support tool used for assisting en-route air traffic controllers by generating resolutions for dual aircraft conflicts after being integrated ... -
Emission Benefits of Continuous Descent Approach
(World Scientific And Engineering Acad And Soc, 2009)The approach phase often has the most fuel savings potential among the other phases such as takeoff, climbout, cruise and ground operations. Therefore, the main objective of this study is to investigate being close to the ... -
Application of Artificial Neural Network (ANN) method to exergy analysis of thermodynamic systems
(IEEE Computer Soc, 2009)Exergy is a way to sustainable development and may be defined as the maximum theoretical useful work, while exergy analysis identifies the sources, the magnitude and the causes of thermodynamic inefficiencies within each ... -
Exergy analysis of a turbofan aircraft engine
(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 ... -
Exergoeconomic analysis of an aircraft turbofan engine
(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 ... -
Emissions at Busy Airports
(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 ... -
Uçuş Gecikmeleri ve Havayolu İşletmelerinin Maliyetleri Üzerindeki Etkileri
(2009)Havayolu işletmeleri ticari amaçlarla taşımacılık yaparlar. Bu nedenle, maliyetleri üzerinde etkili olan faktörlere karşı duyarlıdırlar. Bu faktörlerin en önemlilerinden biri de uçuş gecikmeleridir. Uçuş gecikmeleri havayolu ... -
Energy and emission assessments of continuous descent approach
(Emerald Group Publishing Limited, 2010)Purpose - Continuous descent approach (CDA) is a method, which allows the aircraft flying its individual optimal vertical profile down to runway threshold with engines operating at low-thrust power. The main objective of ... -
Managing corporate sustainability: Risk management process based perspective
(Academic Journals, 2010)Sustainability risk management requires holistic and systematic integration of ecological, socioeconomic, and corporate risk factors in the business management. This paper presents an integrative conceptual framework for ... -
Causal relationship between macro-economic indicators and stock exchange prices in Pakistan
(Academic Journals, 2010)Stock market plays an important role in the economic development of a country. A number of studies have been investigated on the causal relationship between macro-economic indicators and stock exchange prices. But in the ... -
