Abstract
A turbine engine has an engine case with an inlet and an interior of the engine. A bearing is disposed on a portion of the engine case. A fan is disposed within the engine and rotates with operation of the engine. The fan includes a plurality of fan blades, and each fan blade is secured at a first end to a disk. A second end of each fan blade is disposed adjacent to the bearing. The portion is oriented relative to the fan such that a reaction force of a fan blade impacting the bearing is directed axially or away from the inlet.
