Abstract

L'invention concerne une turbomachine (1) double flux comprenant : - une soufflante (3) générant un flux d'air et comprenant une rangée annulaire d'aubes de soufflante (13) portées par un rotor (14) d'axe longitudinal X, - un bec de séparation (10), en aval de la rangée d'aubes de soufflante, séparant le flux d'air en un flux primaire circulant dans une veine primaire (6) annulaire et en un flux secondaire circulant dans une veine secondaire (7) annulaire, et - au moins un compresseur (9) agencé en aval d'une entrée de la veine primaire. Selon l'invention, la turbomachine comprend une rangée annulaire d'aubes partielles (20) mobiles s'étendant sensiblement radialement depuis le rotor et étant agencée axialement entre la rangée annulaire ou la dernière des rangées annulaires d'aubes de soufflante et l'entrée de la veine primaire, chaque aube partielle présentant une hauteur inférieure ou égale au moins à une hauteur de l'entrée de la veine primaire.The invention relates to a double flow turbomachine (1) comprising: - a fan (3) generating an air flow and comprising an annular row of fan blades (13) carried by a rotor (14) of longitudinal axis X , - a separation nozzle (10), downstream of the row of fan blades, separating the air flow into a primary flow circulating in a primary annular vein (6) and into a secondary flow circulating in a secondary vein (7) annular, and - at least one compressor (9) arranged downstream of an inlet of the primary vein. According to the invention, the turbomachine comprises an annular row of movable partial blades (20) extending substantially radially from the rotor and being arranged axially between the annular row or the last of the annular rows of fan blades and the inlet of the primary vein, each partial blade having a height less than or equal at least to a height of the entry of the primary vein.
