Abstract:
1. A moving blade support jig for supporting a gas turbine moving blade on a support apparatus for measurement of a flow rate, said gas turbine moving blade having a hollow passage formed in an interior thereof for introduction of a cooling medium, and said gas turbine moving blade also having a cooling medium inflow port formed at a bottom surface of an embedded portion thereof to be embedded in a rotor, said cooling medium inflow port communicating with said passage, said moving blade support jig comprising: a frame fixed to a moving blade support apparatus and having an inclined holding surface formed at an inner peripheral surface thereof; and peripheral surface thereof; and a sealing member fitted to and held by an outer periphery of said embedded portion of said gas turbine moving blade, and having formed at an outer peripheral surface thereof an inclined support surface in engagement with said inclined holding surface of said frame, and wherein said sealing member is inserted into said frame, with said inclined support surface being fitted to said inclined holding surface, and said gas turbine moving blade is pressed toward said frame, whereby said inclined support surface is fitted to said inclined holding surface, with a surface contact pressure being generated therebetween, so that said gas turbine moving blade is tightly held by said frame.
