RISTwo Phase Flow Heat Transfer and Pressure Drop in Horizontal Scavenge Pipes in an Aero engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In modern aeroengines, the lubrication system plays a key role due to the demand for high reliability. Oil is used not only for the lubrication of bearings, gears, or seals but it also removes large amounts of the generated ...
Ejector Application for Scavenging of an Aero Engine Bearing Chamber
Publisher: The American Society of Mechanical Engineers (ASME)
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 ...
Active Outer Ring Cooling of High Loaded and High Speed Ball Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Bearings for aero engine applications are subjected to a high thermal impact because of the elevated speeds and loads. The high rate of heat generation in the bearing cannot be sustained by the materials used and, in the ...
Ejector Scavenging of Bearing Chambers. A Numerical and Experimental Investigation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Oil system architecture in aero engines has remained almost the same for the last 30 years. At least one oil feed pump is responsible for distributing pressurized oil into the bearing chambers, and several scavenge pumps ...
