Exergetic sustainability assessment of a HALE UAV using dodecene fuel
(Inderscience Enterprises LTD, 2016)
Exergetic sustainability performances of a high altitude long endurance (HALE) unmanned aerial vehicle (UAV), having a single turbofan engine and using dodecene as its fuel were investigated all along its flight profile, ...
Flight control and flight experiments of a tilt-propeller VTOL UAV
(SAGE Publications LTD, 2018)
The purpose of this work is to present a study on the stability and control of an unmanned, fixed wing, vertical take-off and landing aerial vehicle. This airplane is driven by a fixed-pitch tilt-propeller system with the ...
Comparison of Air Transportation Systems of Turkey and Spain as the Competitors in Tourism Sector
(Akdeniz University, 2017)
The growth of air transportation in a country affects positively the development of other industries especially tourism. Turkey and Spain rank among the top countries in the world with their most developed air transportation ...
0-1 integer programming model for procedural separation of aircraft by ground holding in ATFM
(Elsevier France-Editions Scientifiques Medicales Elsevier, 2014)
This study presents a 0-1 integer programming model for air traffic flow management. The model is used for determining optimum departure times of aircraft so as to avoid aircraft conflicts and to balance capacity and demand ...
Assessment of degradation effects for an aircraft engine considering exergy analysis
(Pergamon-Elsevier Science LTD, 2017)
Despite the improvements in engine technology, the combustion processes and wear occurred in engine components affect performance adversely. The turbine and compressor fouling, degradation mechanisms such as erosion, ...
Identification and quantification of reaction phases at Si3N4-Ti interfaces by using analytical transmission electron microscopy techniques
(Elsevier Sci LTD, 2013)
Silicon nitride (Si3N4) and titanium (Ti) were successfully bonded by using a capacitor discharge joining method. The resulting sample interfaces were characterized by scanning electron microscopy (SEM) and analytical ...
Failure analysis of landing gears strut bearings
(Pergamon-Elsevier Science LTD, 2017)
This paper analyses TB 20 training aircraft main landing gear attachment bearings which were failed as a result of cracks. Strut bearing is an attachment fitting of landing gear which attached to the wing spar and secures ...
Characterization of the interfaces formed at the silicon nitride superalloy joints
(Australian Ceramic Society, 2017)
In this study, silicon nitride ceramics (Si3N4) were joined by using a capacitor discharge technique with an Inconel 718 superalloy interlayer and heat-treated in order to determine possible reactions between these two ...
Comparison of Shape Optimization Techniques Coupled with Genetic Algorithm for a Wind Turbine Airfoil
(IEEE, 2016)
Airfoil optimization is an important subject for wind turbines in order to increase the flow efficiency along the blade sections. The first important subject for airfoil shape optimization is the mathematical description ...
New Model for the Optimization of Runway Orientation
(Asce-Amer Soc Civil Engineers, 2014)
One of the most significant factors that affects the location of airport elements is the optimum runway orientation. In this study, a new model called Calculation of Optimum Runway Orientation (CORO) is developed with an ...
