A gas turbine engine includes an engine core, a power gearbox, and a lubrication system. The engine core is configured to drive rotation of at least one shaft. The power gearbox is configured to transfer torque from the at least one shaft to other parts of the gas turbine engine. The lubrication system is configured to deliver lubrication to the power gearbox to reduce friction and cool rotating components within the power gearbox.
