Abstract (en)
The guide blade assembly (1) has multiple rotatable guide blades (2), an inner ring (4) with two half-rings for radial inner stabilization of the guide blades, and a circular seal carrier (8). The shaped elements (6) are inserted in opposite recesses of the half ring segments, which cooperate with wall sections of the recesses in a form-fit or force-fit manner. The half ring segments have a centering section (26), on which a guide blade is guided in each case. An independent claim is included for a method for mounting a guide blade assembly.
