Abstract
A curvature adjustment method is applied to an arc-shaped stator vane segment having a plurality of stator blades disposed side by side on the outer peripheral side of an arc-shaped inner coupling member. In the curvature adjustment method, a jig preparation step, a jig mounting step, and a curvature adjustment step are executed. In the jig preparation step, a curvature adjustment jig and a distance adjustment mechanism are prepared. In the jig mounting step, with the distance adjustment mechanism placed on the inner peripheral side of the inner coupling member, a first end is fixed at a first position of the inner coupling member, and a second end is fixed at a second position of the inner coupling member. In the curvature adjustment step, the distance adjustment mechanism is operated after the jig mounting step to change the distance between the first and second ends of the curvature adjustment jig.
