Abstract

L’invention concerne un module de turbomachine d’aéronef, comportant une soufflante comprenant des aubes à calage variable, et un système de changement de pas qui comprend un dispositif de transfert (94) de fluide d’alimentation d’un moyen de commande agissant sur les aubes. Le dispositif de transfert, agencé en amont d’un réducteur de vitesse, comprend une partie stator (96) et une partie rotor (97), le module comprenant un équipement statorique (98, 99) recevant avec étanchéité et en aveugle une portion de la partie stator, l’équipement statorique comprenant deux conduites (124, 125) en communication fluidique avec deux canalisations (119, 120) de la partie stator, la portion de la partie stator étant fixée de manière amovible sur l’équipement statorique par un organe de fixation assurant une coïncidence, avec étanchéité, des canalisations et conduites. Figure pour l’abrégé : Figure 2The invention relates to an aircraft turbomachine module, comprising a fan comprising variable pitch blades, and a pitch change system which comprises a device (94) for transferring fluid supplying a control means acting on the blades. The transfer device, arranged upstream of a speed reducer, comprises a stator part (96) and a rotor part (97), the module comprising stator equipment (98, 99) receiving with sealing and blind a portion of the stator part, the stator equipment comprising two pipes (124, 125) in fluid communication with two pipes (119, 120) of the stator part, the portion of the stator part being removably fixed on the stator equipment by a fixing member ensuring coincidence, with sealing, of pipes and conduits.
