Open and closed loop control of a transport aircraft after component failure
(2011)Aircraft dynamics are severely affected by the damages and failures of components. If corrective commands are not supplied immediately, force and moment imbalances lead into catastrophic consequences. In this study, flight ... -
Parallel solution of low aspect ratio rectangular flat wings in compressible flow
(2005)Two block parallel Navier Stokes solutions of an aspect ratio 1.0 flat plate with sharp edges are obtained at different Mach numbers and angles of attack. Reynolds numbers are of the order of 200,000-300,000. The flow field ... -
Performance figures of merit for turbojet/fan transport aircraft performance comparison and conceptual design
(2003)A set of aircraft performance figures of merit for different phases of flight mission is derived from aircraft performance equations. In addition, an overall performance figure of merit combining the derived performance ... -
Pitch rate damping of an aircraft by a fuzzy PD controller
(2010)Aircraft dynamics are in general nonlinear, time varying, and uncertain. A control system (classical control systems) designed for a flight condition, may not provide the desired stability and performance characteristics ... -
The role of cyclic mechanical loading and thermal gradients in damage behavior of thermal barrier coating systems
(2005)Ceramic thermal barrier coatings (TBC) can exhibit premature in-service failure due to spallation as a consequence of exposure to elevated temperatures, aggressive environments, and cyclic thermal and mechanical loading. ... -
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 ... -
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 ... -
The use of information technologies and systems in airlines
(2009)All over the world, air passengers would like to determine their destination, prefer an airline company among the many in the world, buy their tickets without any difficulty and make any changes when necessary. Then they ... -
Zaman Serilerinde NARX Sinir Ağları Modeliyle Uçuşa Elverişlilik Süresinin Kestirimi
(Institute of Electrical and Electronics Engineers Inc., 2017)Havacılık planlamalara yo˘gun bir ¸sekilde ba¸svurulan ciddi bir sektördür. Yüksek maliyetlere sebep olabilecek plansızlı˘gın giderilmesi ve vahim sonuçlar do˘gurabilecek kazaların önüne geçilebilmesi için öngörülere ...
