Abstract (en)
[origin: CA2976932A1] An assembly for the stator of a compressor of an axial-flow turbine engine, such as a low-pressure compressor of the turbojet engine, also known as a booster,includes: a first annular array of first vanes of the stator extending radially in the axial flow; and a second annular row of second vanes of the stator, with controlled orientation, also known as variable-pitch vanes or VSV. In addition, the assembly includes an external monobloc shroud on which the first vanes and the second vanes are mounted in a pivoting manner.
Abstract (fr)
L'invention concerne un ensemble pour stator (22) de compresseur de turbomachine à flux axial, par exemple un compresseur basse pression du turboréacteur également appelé booster. L'ensemble comprend : une première rangée annulaire de premières aubes (26) de stator (22) s'étendant radialement dans le flux axial ; et une deuxième rangée annulaire de deuxièmes aubes (28) de stator (22) à orientation pilotée, également appelées aubes à calage variable ou VSV. En complément, l'ensemble comprend une virole externe monobloc sur laquelle les premières aubes (26) et les deuxièmes aubes (28) sont montées de manière pivotante.
