Abstract: A lubrication system is provided. The lubrication system may be used in conjunction with a gas turbine engine for generating power or lift. The lubrication system utilized a flow scheduling valve which reduces lubricant flow to at least one component based on an engine load. The lubrication system may further include a main pump which may be regulated by an engine speed. Thus, a lubrication system which provides a lubricant to engine components based on the load and speed of the engine is possible. The system may improve efficiency of the engine by reducing the power previously spent in churning excess lubricant by at least one engine component as well as reducing the energy used by a lubricant cooler in cooling the excess lubricant. The lubricant cooler size may also be minimized to reduce weight and air drag due to the reduced lubricant flow.

Abstract: A lubrication system for a gas turbine engine is provided. The lubrication system includes a supply source of a fluid lubricant, a main supply pump, and a boost pump system. The main supply pump has an MSP fluid flow inlet port and an MSP fluid flow exit port. The main supply pump is configured to receive a source fluid lubricant flow at a first pressure, and configured to produce a supply fluid flow at a second pressure. The second pressure is greater than the first pressure. The boost pump system has a boost pump having a BP fluid flow inlet port, and a BP fluid flow exit port. The boost pump system is configured so that the boost pump selectively receives at least a portion of the supply fluid flow from the main supply pump at the BP fluid flow inlet port, and the boost pump is configured to produce a boost supply fluid flow at a third pressure at the BP fluid flow exit port, wherein the third pressure is greater than the second pressure.

Abstract: A lubrication system for a gas turbine engine may include a pump for moving a lubricant through a conduit from a lubricant tank to an engine component. Further, a scheduling valve positioned in the conduit between the lubricant tank and the engine component may vary a flow of the lubricant to the engine component based on a condition.

Abstract: An exemplary method of monitoring a position of a lubricant valve in a gas turbine engine includes monitoring a position of a lubricant valve using a first auxiliary pressure reading and a second auxiliary pressure reading. The first auxiliary pressure reading is taken when a primary lubrication circuit is at a first pressure. The second auxiliary pressure reading is taken when the primary lubrication circuit is at a second pressure. An exemplary assembly that detects transitions of a lubricant valve in a gas turbine engine includes a controller that uses readings of the primary pressure and readings of the auxiliary pressure to detect a position of a lubricant valve.
