    Abstract: PROBLEM TO BE SOLVED: To provide a swift and simple method and a related device for replacing a damaged vane assembly located at a rear of the fan of a turbine engine. SOLUTION: A repair device for replacing a vane which cannot be used by a turbine engine has a vane sub-assembly which is provided with an air foil 124 attached with a base connected to a base end part and an opposite base 1 which can be slided on the air foil which can be used. The opposite base 156 is slide toward a connection base through an end part of the air foil 134. The opposite base 156 is fixed to an outside easing with a stud and a nut.

    Abstract: A fan blade comprises an airfoil portion and a sheath portion. The sheath portion has a sheath head section, a first sheath flank, and a second sheath flank, both flanks extending chordwise from the forward sheath section. The sheath portion is bonded to the airfoil portion such that the sheath head section covers the forward airfoil edge, defining a blade leading edge. The first sheath flank covers a portion of the first airfoil surface proximate the airfoil forward edge, jointly defining a blade suction surface. The second sheath flank covers a portion of the second airfoil surface proximate the airfoil forward edge, jointly defining a blade pressure surface. The first metallic material is an aluminum alloy containing between about 0.5 wt% and about 3.0 wt% of lithium.

    Abstract: A repair kit for replacing an unserviceable vane assembly in a turbine engine includes a serviceable vane subassembly (120) having a serviceable airfoil (124) with a base (134) attached to the root end thereof and an opposing base (156) which is unattached to but slidably engagable with the serviceable airfoil. The opposing base is slipped over the tip end of the airfoil and slid toward the opposing base. The vane subassembly and opposing base are pivoted into position between inner and outer engine cases in place of an unserviceable vane assembly so that receptor sockets (148, 150) in the attached base engage support pins (72) extending from the inner case. An adhesive (182) is applied to the tip end of the serviceable airfoil and the opposing base is translated into its installed position near the tip end of the airfoil. Upon curing of the adhesive, the opposing base becomes attached to the airfoil. The base is secured to the outer case by studs (196) and nuts (198).

    Abstract: A fan blade is disclosed comprising a lightweight metallic airfoil portion and a high-strength sheath portion. The airfoil portion has a forward airfoil edge, a first airfoil surface, and a second airfoil surface. The sheath portion has a sheath head section, a first sheath flank, and a second sheath flank, both flanks extending chordwise from the forward sheath section. The sheath portion is bonded to the airfoil portion such that the sheath head section covers the forward airfoil edge, defining a blade leading edge. The first sheath flank covers a portion of the first airfoil surface proximate the airfoil forward edge, jointly defining a blade suction surface. The second sheath flank covers a portion of the second airfoil surface proximate the airfoil forward edge, jointly defining a blade pressure surface.Fig 2.

    Abstract: A workpiece location and support means as described which is free from any tendency to locate the workpiece in a predetermined position. The workpiece is supported and located by a series of hydraulic actuators which in one condition permit the workpiece to move freely but in another hydraulic condition lock the workpiece in one place and do not permit motion thereof. The present invention has particular application as a workpiece support in inertia bonding machines.
