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: A modulating fan air diverter and annular air-oil cooler for a gas turbine engine located in the inner fixed structure adjacent to the core cowl is provided. The fan air diverter modulates between an open position, corresponding to maximum fan nozzle area and airflow through the air-oil cooler, and a closed position, corresponding to minimum fan nozzle area and airflow through the air-oil cooler. As such, the device is capable of supporting dual functions of engine heat management as well as engine performance and fan stability.

Abstract: A method of controlling lubrication flow to a first engine component, a second engine component and a lubrication tank of a gas turbine engine according to an example of the present disclosure includes, among other things, determining more than one condition experienced by the gas turbine engine, comparing with a processor on a controller the more than one condition against an engine performance model stored in memory on the controller, wherein the engine performance model includes stored relationship values between the more than one condition and a position of a scheduling valve, the scheduling valve disposed between the lubricant tank and the first engine component and between the lubricant tank and the second engine component, pumping a lubricant from the lubricant tank through a conduit to the scheduling valve using a pump, and controlling the position of the scheduling valve to vary a flow of the lubricant to two or more of the first engine component, the second engine component and the lubrication tank based upon the comparing of the more than one condition experienced by the gas turbine engine.

Abstract: A lubrication system for a gas turbine engine according to an example of the present disclosure includes, among other things, a pump that moves a lubricant, a lubricant tank that stores the lubricant, a first engine component and a second engine component each requiring lubrication from the lubricant, a conduit between the lubricant tank and the first engine component and between the lubricant tank and the second engine component, a scheduling valve positioned in the conduit between the lubricant tank, and the first engine component and the second engine component, and a controller including a memory and a processor that controls the scheduling valve, wherein the memory includes an engine performance model, wherein the engine performance model includes stored relationship values between more than one condition experienced by the gas turbine engine during operation and a position of the scheduling valve, and wherein the scheduling valve varies a flow of the lubricant to the first engine component, the second engine component and the lubrication tank based on comparing the more than one condition with the engine performance model.

Abstract: An air-oil cooler for a gas turbine engine includes an air cooling structure and a lubricant channel. The lubricant channel extends between a lubricant inlet and a lubricant inlet and is bounded by the air cooling structure. The air cooling structure has an arcuate shape for circumferentially spanning a portion of a gas turbine engine core.
