Abstract
A shaft assembly (which may be a rotor mast for a rotorcraft) may include a shaft body formed with composite material and one or more metal fittings attached to the shaft body. A metal fitting may include an interior opening with a cross-section having a non-circular perimeter (such as an oval or an ellipse). The interior opening may also include contouring, such as a first tapered section in which the fitting converges toward the longitudinal axis of the shaft body and a second tapered section in which the fitting diverges from the longitudinal axis.
