Abstract: A gas turbine engine according to an exemplary aspect of the present disclosure includes, among other things, a passageway configured to permit fluid to drain back into a bearing compartment. The passageway has an inlet outside the bearing compartment and an outlet inside the bearing compartment. The outlet is spaced-apart from a central rotational axis of a towershaft gear.

Abstract: An airfoil bonding system may comprise a mold tool configured to support an airfoil assembly during a bonding process. The bonding process may include applying heat and pressure to the airfoil assembly. A surface of the mold tool may complement a preselected airfoil parameter. The mold tool may maintain the airfoil assembly in the preselected airfoil parameter during the application of heat and pressure to the airfoil assembly.
