Mixed Stator for an Axial Turbine Engine Compressor

摘要

The present application relates to a stator for a low-pressure compressor of an axial turbine engine. The stator includes an annular row of stator vanes with connection vanes, and support vanes which are grouped into vaned casings. The casings include internal platforms and external platforms, and are integrally produced by means of additive production based on titanium powder. The stator has a circular internal shroud which is formed by the internal platforms of the vanes of the casings and internal shroud segments which are fixed to the connection vanes. The internal platforms include pairs of contact surfaces in order to interlock the shroud segments therein by moving into abutment and sliding against the contact surfaces. The contact surfaces are perpendicular to the rotation axis and form axial stops.

1. A stator assembly for an axial turbine engine, comprising:
an annular row of stator vanes comprising:
integral support vanes with internal platforms and connection vanes;internal shroud segments;an internal shroud formed by the internal platforms of the support vanes; andinternal shroud segments which are fixed to the connection vanes; wherein an internal platform of a support vane comprises:
at least one contact surface which is generally perpendicular to the rotation axis of the turbine engine and which is axially in contact with an internal segment.
