Title (EN) AIRCRAFT TURBOMACHINE EXIT GUIDE VANE COMPRISING A BENT LUBRICANT PASSAGE OF IMPROVED DESIGN
(FR) AUBE DIRECTRICE DE SORTIE POUR TURBOMACHINE D'AERONEF, COMPRENANT UNE ZONE COUDEE DE PASSAGE DE LUBRIFIANT PRESENTANT UNE CONCEPTION AMELIOREE
Abstract:
(EN) The invention relates to a guide vane (24) for an aircraft bypass turbomachine, the aerodynamic part (34) thereof comprising a first internal lubricant cooling passage (50a) in which heat transfer means are arranged and a second internal lubricant cooling passage (50b) in which heat transfer means are arranged, the aerodynamic part comprising a bent zone (54) connecting a lubricant outlet end of the first internal passage (50a) to a lubricaant inlet end of the second passage (50b), the bent zone extending along a curved generatrix and being in part delimited by the intrados wall and by the extrados wall of the vane. According to the invention, the bent zone (54) comprises one or more lubricant guides (84) arranged between the intrados and extrados walls of the vane and each running substantially parallel to the curved generatrix of the bent zone (54).
(FR) L'invention concerne une aube directrice (24) pour turbomachine d'aéronef à double flux, sa partie aérodynamique (34) comportant un premier passage intérieur (50a) de refroidissement de lubrifiant dans lequel sont agencés des moyens de transfert thermique ainsi qu'un second passage intérieur (50b) de refroidissement de lubrifiant dans lequel sont agencés des moyens de transfert thermique, la partie aérodynamique comprenant une zone soudée (54) reliant une extrémité de sortie de lubrifiant du premier passage intérieur (50a) à une extrémité d'entrée de lubrifiant du second passage (50b), la zone coudée s'étendant le long d'une génératrice courbe et étant en partie délimitée par la paroi d'intrados et par la paroi d'extrados de l'aube. Selon l'invention, la zone coudée (54) comprend un ou plusieurs guides de lubrifiant (84) agencés entre les paroi d'intrados et d'extrados de l'aube, et s'étendant chacun sensiblement parallèlement à la génératrice courbe de la zone coudée (54).
