Guide vane assembly vane box of an axial turbine engine compressor

摘要

The invention relates to an angular sector of a bladed stator of a low-pressure compressor of an axial turbine engine. The sector comprises an outer shroud and an inner shroud in the form of circular arcs intended to be mounted in a concentric manner on the outer casing of the turbine engine compressor. The sector likewise comprises a row of stator vanes extending radially and anchored in the shrouds in such a manner as to form a bladed box. The vanes of the box comprise anchoring lugs at their outer ends, the lugs being disposed in the thickness of the outer shroud. The inner shroud comprises stubs for anchoring vanes.

1. An angular sector of a bladed stator of an axial turbine engine, said sector comprising:
an arcuate segment of an outer shroud intended to be mounted on a casing of the turbine engine; an arcuate segment of inner shroud; and a row of stator vanes extending radially from the outer shroud to the inner shroud, each of the stator vanes comprising an inner anchoring portion anchored to the inner shroud and an outer anchoring portion anchored to the outer shroud in such a manner that the stator vanes, the inner shroud and the outer shroud form a bladed box, wherein
at least one anchoring portion of a box vane comprises an anchoring lug which mainly extends in the circumferential direction toward a neighboring vane over at least half the width of the space between the neighboring vanes, and which is disposed in the thickness of one of the shrouds in such a manner as to anchor the vane to the shroud to make the box rigid.
