Abstract
BASCULEMENT DIFFERENCIÉ ENTRE ROTOR ET STATOR AUX ENTREFERS ROTOR-STATOR DANS UN COMPRESSEUR DE TURBOMACHINE Compresseur de turbomachine axiale, comprenant une alternance de rangées d’aubes statoriques et rotoriques, avec des plateformes annulaires (22.2, 26.2) intérieures à la veine fluide et délimitant ladite veine ; au moins une des plateformes annulaires statoriques (22.2) et au moins une des plateformes annulaires rotoriques (26.2) présentant un profil longitudinal extérieur (22.3, 26.3) incliné (IS i/IRi) vers l’intérieur et vers l’amont par rapport à un profil nominal (N) de la veine fluide. L’inclinaison (IRi) du profil longitudinal extérieur (26.3.2) de l’au moins une plateforme annulaire rotorique (26.2) est supérieur à l’inclinaison (IS i) du profil longitudinal extérieur (22.3) et/ou l’arrondi (RS i) de l’au moins une plateforme annulaire statorique (22.2), respectivement. (Figure à publier avec l'abrégé : Figure 6)
