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.
A repair kit for replacing an unserviceable stator vane assembly in a gas turbine engine having an array of vane assemblies extending across an annular flowpath defined by coaxial inner and outer cases, the unserviceable vane assembly having an airfoil with inner and outer ends, an inner base attached to the inner end of the airfoil and secured to the inner case, an outer base attached to the outer end of the airfoil and secured to the outer case, the repair kit characterized by:
