Summary:The present invention relates to a turbine engine rectifier stage comprising a plurality of fixed vanes connecting an inner ferrule support 19 to an outer ferrule support 14, said inner ferrule support and said outer ferrule support defining an aerodynamic vein and comprising a set of contiguously assembled sectors 20,15 respectively, the plurality of fixed vanes comprising so-called structural vanes 5 surrounding so-called non-structural or aero vanes 6 so as to form boxes 7, said structural vanes 5 being rigidly attached to the ends of the sectors of the inner ferrule support 20 by means of attachment elements 17 in order to impart increased stiffness to the boxes 7. La présente invention a trait à un étage redresseur de moteur à turbine comportant une pluralité daubes fixes reliant un support de virole intérieure (19) à un support de virole extérieure (14), lesdits support de virole intérieure et support de virole extérieure délimitant une veine aérodynamique et comprenant un ensemble de secteurs accouplés de manière jointive (20, 15), respectivement, la pluralité daubes fixes se composant daubes dites structurales (5) encadrant des aubes dites non structurales ou aéro (6) de manière à former des caissons (7), lesdites aubes structurales (5) étant rigidement fixées aux extrémités des secteurs du support de virole intérieure (20) au moyen déléments de fixation afin de conférer une rigidité accrue aux caissons (7).
