A ceramic matrix composite material (CMC) vane for a gas turbine engine wherein the airfoil member (12) and the platform member (14) are formed separately and are then bonded together to form an integral vane component (10). Airfoil member and the platform member may be bonded together by an adhesiv

A ceramic matrix composite material (CMC) vane for a gas turbine engine wherein the airfoil member (12) and the platform member (14) are formed separately and are then bonded together to form an integral vane component (10). Airfoil member and the platform member may be bonded together by an adhesive (20) after being fully cured. Alternatively, respective joint surfaces (16, 18) of the green body state airfoil member and platform member may be co-fired together to form a sinter bond (30). A mechanical fastener (38) and/or a CMC doubler (42) may be utilized to reinforce the bonded joint (40). A matrix infiltration process (50) may be used to create or to further strengthen the bond.

The apparatus of claim 9 further including an electric motor in communication with said swivel assembly for moving said swivel assembly vertically along said stanchion. 11. The apparatus of claim 1 wherein said expansion assembly includes a center divider positioned within the interior of said support mandrel and extending longitudinally therethrough said center divider having a top and a base. 12. The apparatus of claim 11 wherein the base of said center divider is attached to said pivot rod. 13. An apparatus for moving an object having a bore therein defined by walls of the object from a first position to a second position, comprising: a) a support mandrel for being positioned in the bore at the first position in advance of moving the object, wherein said support mandrel comprises a hollow cylinder having an interior and exterior; b) an expansion assembly cooperating with said support mandrel for varying a lateral dimension of the support mandrel while positioned in the bore between a bore insertion dimension at which the support mandrel may be inserted into and withdrawn from the bore, and a bore engaging dimension at which the support mandrel engages the walls of the object defining the bore and locks the support mandrel and the object together against relative movement, wherein said expansion assembly includes a center divider positioned within the interior of said support mandrel and extending longitudinally therethrough, said center divider having a top and a base, and further wherein said expansion assembly includes a first roller longitudinally positioned in the top of said center divider for facilitating insertion of said support mandrel into said bore and withdrawal therefrom; and (c) a swivel assembly which the support mandrel is connected for movement from the first position to the second position whereby the object carried by the support mandrel is moved in unison with the movement of the support mandrel and is released by the support mandrel at the second position. 14. The apparatus of claim 13 further including a guiding member positioned longitudinally within the interior of said support mandrel and attached to one of said semi-cylindrical plates, said guiding member having an inclined surface. 15. The apparatus of claim 14 wherein said expansion assembly includes: (a) a sliding member contained within said center divider for longitudinally moving within said support mandrel; and (b) a second roller attached to said sliding member, said second roller positioned within said support mandrel in axial alignment with said guiding member such that said second roller contacts said guiding member and urges said semi-cylindrical plate to pivotally move outward as said sliding member moves in a direction of increased inclination of said guiding member whereby said semi-cylindrical plate contacts and frictionally engages said walls defining said bore. 16. An apparatus for moving an object having a bore therein defined by walls of the object from a first position to a second position, comprising: (a) a support mandrel for positioned in the bore at the first position in advance of moving the object; (b) an expansion assembly cooperating with said support mandrel for varying a lateral dimension of the support mandrel while positioned in the bore between a bore insertion dimension at which the support mandrel may be inserted into and withdrawn from the bore, and a bore engaging dimension at which the support mandrel engages the walls of the object defining the bore and locks the support mandrel and the object together against relative movement, said expansion assembly comprising two semi-cylindrical plates connected to a pivot rod wherein said expansion assembly varies said lateral dimension of said support mandrel from said bore insertion dimension to said bore engaging dimension by urging said semi-cylindrical plates to pivotally move outward to frictiona
