Segment with minimum two blades, turbine element and method to mount a segment

摘要

The segment has a blade (1) with a blade root (3) that is detachably connected with a blade root (4) of a blade (2) by a mechanical connecting unit (15). The mechanical connecting unit is formed in the form of a bolt connection e.g. screwed fastening. The blade root (3) is adjacent to the blade root (4), where contact surfaces of the blade roots have a centering unit. The blade roots are arranged on a ring circumference (27) and are oriented along a ring radius (29). An independent claim is also included for a method for assembling of a segment.
