Abstract
Etage d'aubes statoriques (39) dans un compresseur (10), comprenant des aubes de redresseur (24) sensiblement radiales réparties régulièrement autour de l'axe du compresseur (10) et portées par une virole interne (20) et/ou une virole externe (22), caractérisé en ce qu'il comprend également des aubes intermédiaires (40) s'étendant radialement entre les aubes précitées (24) et ayant une longueur axiale et/ou une hauteur radiale inférieures à celles des aubes de redresseur (24).
