Abstract
Disclosed is a lubricant supply system for a plurality of bearing dampers in a plurality of engine bearing compartments of a gas turbine engine, including a lubricant supply conduit, a first lubricant delivery conduit fluidly coupled to the supply conduit, the first delivery conduit including one or more lubricant delivery flow paths and delivering lubrication to engine components, a second lubricant delivery conduit fluidly coupled to the supply conduit, the second delivery conduit delivering lubricant to one or more of the plurality of bearing dampers, and an active oil flow management valve, selectively restricting lubricant flow in the first delivery conduit, increasing pressure in the second delivery conduit, based on an engine shaft rotational speed.
