Abstract: Oil system architecture in aero engines has remained almost the same for the last 35 years. At least one mechanically-driven oil feed pump is responsible for distributing pressurized oil into the bearing chambers and several ...

Abstract: In modern aeroengines, the lubrication system holds a key role due to the demand for high reliability standards. An aeroengine bearing chamber contains components like bearings and gears. Oil is used for lubrication and ...

Abstract: This work presents an exergy analysis and performance assessment of three recuperative thermodynamic cycles for gas turbine applications. The first configuration is the conventional recuperative (CR) cycle in which a heat ...
