Abstract
A gas turbine engine includes a rotating shaft. An oil scoop rotates with the rotating shaft. The oil scoop has end walls spaced axially along an axis of rotation of the rotating shaft and an axially central recess. A duct is spaced radially outwardly of the oil scoop. The duct has an oil inlet, with an oil supply nozzle to supply oil into the oil inlet in the duct. The oil inlet is then connected to supply oil into the recess. The oil scoop has an inner hole to allow oil to flow from the recess to an outer periphery of the shaft.
