Concurrent Aircraft Routing and Maintenance Scheduling Using Goal Programming
(Gazi University, Fac Engineering Architecture, 2012)An effective competition at the civil aviation sector could be possible by an effective fleet management. One of two important functions of the fleet management is to define the aircraft routes and plan the aircraft ... -
Defect evolution in thermal barrier coating systems under multi-axial thermomechanical loading
(Elsevier Science Sa, 2005)In service, gas turbine components with thermal barrier coatings experience high cyclic mechanical and thermal loading. Important, but not yet considered sufficiently, are the multi-axial stresses arising from thermal ... -
Dwell time effect on fatigue crack growth of RR1000 superalloy
(Taylor & Francis LTD, 2007)The requirement for improved understanding of the behaviour of turbine disc alloys at elevated temperatures has led to an increased interest in the contribution of time dependant mechanisms to high temperature fatigue crack ... -
Failure analysis of an aircraft piston engine components
(Pergamon-Elsevier Science LTD, 2009)In this study, failed parts from the piston engine of TB-20 Trinidad aircraft which declared an emergency landing to Anadolu University Airport, Eskisehir, Turkey due to the over-speed of propeller during a training flight ... -
Fatigue cracks in a thermal barrier coating system on a superalloy in multiaxial thermomechanical testing
(Elsevier Sci LTD, 2008)Thermal barrier coatings (TBC,) are applied on cooled gas turbine components. Between the heated and cooled surfaces a thermal gradient develops, resulting for constraint components in high multiaxial stresses, which may ... -
High temperature bending creep behavior of a multi-cation doped alpha/beta-SiAlON composite
(Elsevier Sci LTD, 2011)SiAlON ceramics with high hardness and high toughness can be made through designing alpha/beta-SiAlON composites. An important advantage of alpha-SiAlON phase is that the amount of intergranular phase is reduced by the ... -
Marching distance functions for smooth control of hyperbolic grids
(Amer Inst Aeronaut Astronaut, 2000)… -
Microstructural observation of overload effect on the fatigue crack growth of 2024-T3 Al-alloy
(IOP Publishing LTD, 2004)Microstructural investigation of fracture surfaces after fatigue crack growth experiments on 2024-T3 centrally cracked specimens was carried out. Variable amplitude loadings were used with periodic overload cycles added ... -
Multiaxial thermo-mechanical fatigue on material systems for gas turbines
(Wiley-V C H Verlag GMBH, 2007)Material systems made from nickel based superalloys with protective coatings have been tested in thermo-mechanical fatigue with superposed thermal gradients, which generated multiaxial stress states. The testing conditions ... -
NARX Neural Networks Based Time Series Prediction for Amount of Airworthiness Time
(IEEE, 2016)Aviation, a serious sector, is required to recourse planning intensively. There is a need for foresight in order to eliminate the planless that can lead to high costs and prevent accidents that could cause to fatal ... -
Scanning electron microscopy observations of fatigue crack growth retardation due to block overloads
(IOP Publishing LTD, 2001)Fatigue crack propagation behaviour of 2024-T3 aluminium (Al) alloy under periodic overloads superimposed on constant amplitude loadings with R=0.5 and f=10 Hz was investigated by scanning electron microscopy (SEM). During ... -
Testing and characterization of ceramic thermal barrier coatings
(Trans Tech Publications LTD, 2005)This paper gives a short overview of tests applied for the investigation of long term behaviour of thermal barrier coating systems. A variety of tests has been conducted on an exemplary material system with the coatings ... -
Thermoeconomic Analysis of Farine Mill in Dry Type Cement Production
(Turkish Soc Thermal Sciences Technology, 2010)Thermoeconomics is the cost analysis based on the cost and exergy calculations which are used to determine the potential of unproductiveness in all of the thermal systems. This approach is also defined as 'exergy cost' and ... -
Time-economic lifetime assessment for high performance thermal barrier coating systems
(Trans Tech Publications LTD, 2007)Strategies for time-economic lifetime assessment of thermal barrier coatings (TBC) in service are described and discussed on the basis of experimental results, achieved on material systems with coatings applied by electron ... -
Training of the maintenance personnel to prevent failures in aircraft systems
(Pergamon-Elsevier Science LTD, 2011)The aircraft maintenance process plays a vital role in aviation safety. The quality of the maintenance process and the qualifications of the aircraft maintenance personnel are important factors in the safety of aircraft. ...
