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 ...
Impact of aircraft performance characteristics on air traffic delays
(2004)
Air transportation has been suffering for decades from delays caused by air traffic congestion. This paper presents the effect of aircraft performance differences on air traffic delays. Rate of climb and cruising speeds ...
Aero-propulsive modeling of transport aircraft for air traffic management applications
(2004)
Aerodynamic and propulsive modeling of current aircraft fleet is vital for Air Traffic Management applications, especially for use in decision support tools to predict aircraft trajectories and simulation tools. There are ...
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 ...
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 ...
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. ...
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 ...

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 ...
