Effect of polyamide ratio on the flammability of wool/PA blended aircraft seat fabrics
(IOP Publishing LTD, 2018)Wool and polyamide blended fabrics are widely preferred for aircraft seats. Due to the requirements of the flammability regulations of airline authorities, aircraft fabrics have to pass vertical flammability and smoke ... -
Sustainability assessment in piston-prop helicopter engine
(Springer International Publishing, 2016)About 75% of the world’s energy requirement is provided by fossil fuels, and there are various improvement efforts in all fields to ensure the effective use of available sources, taking into consideration the gradual ... -
Exergetic Destruction Effects Of Operating Conditions On The Turbojet Engine Components
(Trans Tech Publications LTD, 2012)The minimization of exergy destruction brings the design as closely as permissible to the theoretical limit. This study presents exergy destruction analysis of a turbojet engine for different flight Mach number and altitudes. ... -
Exergetic and Energetic Response Surfaces for Small Turbojet Engine
(Trans Tech Publications LTD, 2012)Exergy analysis permits meaningful efficiencies to be evaluated for a system or process, and the sources, causes and locations of thermodynamic losses to be determined. This study presents exergetic modeling of a small ... -
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 ... -
Ink-jet printability of aqueous ceramic inks for digital decoration of ceramic tiles
(Elsevier Sci LTD, 2016)Digital decoration of ceramic tiles has turned to be a prevalent and dynamic technology in the last decade. Current printers use drop-on-demand (DOD) ink-jet print heads (UP) fed with solvent-based inks containing ceramic ... -
