    Abstract: A gas turbine engine (20) and method for containing a fan inside an engine after a fan thrust bearing assembly failure. The engine (20) may comprise a fan (42), a housing (100) including a compartment (102), a fan shaft (104) inside the compartment (102) and comprising a bowl (108), a support structure (110) inside the compartment (102), a speed sensor pickup (114) mounted on the outer surface (120) of the bowl (108), a speed sensor (112) mounted on the support structure (110), and a fan thrust bearing assembly (41) disposed forward of the bowl (108). The fan thrust bearing assembly (41) including a bearing (126). The speed sensor (112) and the sensor pickup (114) define a defining a sensor gap (116). The bearing (126) and the outer surface (120) defining a fan thrust bearing gap (130), wherein the sensor gap (116) is less than the fan thrust bearing gap.

    Abstract: What is described is a system for pumping lubricant to a component of a gas turbine engine (20). The system includes a fan gear (200; 600) coupled to a fan shaft (98) of the gas turbine engine (20) and configured to rotate in a forward direction and in a reverse direction based at least partially on a direction of wind relative to a fan (42) of the gas turbine engine (20). The system also includes a first pump (206; 606) coupled to the fan gear (200; 600) and configured to pump lubricant to the component in response to the fan (42) rotating in the forward direction. The system also includes a second pump (208; 604) coupled to the fan gear (200; 600) and configured to pump lubricant to the component in response to the fan (42) rotating in the reverse direction.

    Abstract: A gas turbine engine assembly includes, among other things, a clutch configured to move from a first position to a second position in response to rotation of a gas turbine engine fan at a speed greater than a threshold speed. Whether the clutch is in the first position or the second position, the clutch permits rotation of the gas turbine engine fan in a first direction. When the clutch is in the first position, the clutch limits rotation of the gas turbine engine fan only in an opposite, second direction. The clutch is disposed within a compartment that is accessible and removable via removal of an aft engine cover structure. The clutch is removable on-wing.
