Abstract: The present invention provides a turbofan engine including leading edge erosion protection for composite stator vanes contained therein. The composite stator vanes are defined by a leading edge, a trailing edge, a concave surface and a convex surface. The vanes are generally formed of a graphite fiber and an aramid fiber braided preform that is laminated with an epoxy matrix resin or other high temperature matrix resin. A wire mesh screen is embedded during a molding process into an outermost surface of the leading edge of the epoxy matrix resin. A tapering erosion protection layer comprised of an erosion protective material is applied to the wire mesh screen at the leading edge of the composite stator vane an aids in protecting the leading edge of the stator vane from debris and contaminants, including operational fluids, dust, and sand that may be carried in an air stream passing therethrough the turbofan engine, as well as an erosive operational environment.

Abstract: An adjustable and lockable bushing assembly includes a locking plate and a bushing. The locking plate has a bushing engagement opening that is defined by a plurality of first serrations, and a boss that extends axially therefrom. The bushing engages the locking plate and includes a concentric section, an eccentric section, a lock interface section, and an opening. The opening has a fixed diameter and extends along a longitudinal axis through the bushing. The concentric section has an outer surface that has a circumference that is concentric with the longitudinal axis. The eccentric section extends from the concentric section has an outer surface that has a circumference that is eccentric with the longitudinal axis. The lock interface section extends from the concentric section and includes an outer surface defined by a plurality of second serrations that engage the first serrations.
