Stator vane for an axial-flow turbomachine and corresponding stator vane assembly

摘要

The blade (10) has a blade root (12) including a projecting shaped piece (24) at a side, and a threaded hole (26) formed in the piece for radial tensioning of the blade in a circumferential groove of a carrier structure of a turbomachine using a tensioning screw. The tensioning screw is screwed into the threaded hole and supported on a bottom of the circumferential groove. The blade root has a recess (29) on another side for accommodating another projecting shaped piece of adjacent stator blade, and has another tensioning screw screwed into the latter piece.
