CA 2747989
The invention relates to a compressor for a turbine engine including a casing (4), at least one compressor stage consisting of a stationary blade (2) impeller and a mobile blade (1) impeller positioned upstream from said stationary blade (2) impeller, and cavities (5) made in said casing opposite the through-path of the mobile blades (1), said cavities having a length L2 measured axially and being shifted upstream relative to the blades (1) so as to generate an overlap with a length L1, characterised in that the lengths L1 and L2 are respectively between 35% and 50% and between 80% and 90% of the axial chord Cax measured at the outer end of the blades (1), and in that the cavities (5) do not in communication with one another.
Compresseur pour turbomachine comprenant un carter (4), au moins un étage de compresseur constitué d'une roue d'aubes fixes (2) et d'une roue d'aubes mobiles (1) positionnée en aval de ladite roue d'aubes fixes (2), et des cavités (5) creusées dans ledit carter en regard du chemin de passage des aubes mobiles (1), lesdites cavités ayant une longueur L2 mesurée axialement et étant décalées vers l'amont par rapport aux aubes mobiles (1) de façon à générer un recouvrement ayant une longueur L1, caractérisé en ce que les longueurs L1 et L2 sont comprises respectivement entre 35 et 50% et entre 80 et 90% de la corde axiale C ax mesurée en extrémité externe des aubes mobiles (1) et en ce que les cavités (5) ne communiquent pas entre elles.
