GAS TURBINE, AND METHOD FOR REPAIRING GAS TURBINE

摘要

A gas turbine is provided with: a heat-insulating ring and a split ring enclosing a channel for high-temperature gas from the outer periphery side; a blade ring, annularly formed on the outer periphery side of the split ring and the heat-insulating ring; and a support member for supporting the split ring and the heat-insulating ring, the support member fitting into a fitting recess formed so as to be recessed from the axial end surface of the blade ring; the inner wall surface of the fitting recess having a first inclined surface, which inclines from an opening edge of the fitting recess so that the width gradually narrows from the axial end surface of the blade ring towards the inside of the blade ring in the axial direction; and the support member having a second inclined surface, which inclines so as to correspond to the first inclined surface.
