Abstract

L'invention concerne un dispositif de modification de calage d'une aube de redresseur dans une turbomachine, ladite turbomachine s'étendant autour d'un axe (X) de la turbomachine et comprenant au moins une aube (2) d'un redresseur (1) comportant une plateforme annulaire externe (4) et une plateforme annulaire interne délimitant une veine d'écoulement (7), l'aube (2) étant montée à rotation autour d'un axe (Y) de sorte à faire varier le calage de l'aube, ledit dispositif comportant au moins un actionneur (9) fluidique configuré pour entraîner l'aube en rotation autour de son axe (Y) et ainsi modifier le calage de l'aube (2), ledit actionneur (9) étant alimenté par un dispositif d'alimentation (19) en fluide sous pression, le fluide sous pression étant de l'air sous pression prélevé de la veine d'écoulement (7), le dispositif d'alimentation (19) comportant au moins un conduit mettant en communication fluidique la veine d'écoulement (7) et l'au moins un actionneur (9).The invention relates to a device for modifying the timing of a stator blade in a turbomachine, said turbomachine extending around an axis (X) of the turbomachine and comprising at least one blade (2) of a stator ( 1) comprising an external annular platform (4) and an internal annular platform delimiting a flow vein (7), the vane (2) being mounted to rotate about an axis (Y) so as to vary the setting of the vane, said device comprising at least one fluidic actuator (9) configured to drive the vane in rotation about its axis (Y) and thus modify the timing of the vane (2), said actuator (9) being supplied by a supply device (19) with pressurized fluid, the pressurized fluid being pressurized air taken from the flow stream (7), the supply device (19) comprising at least one duct placing the flow stream (7) and the at least one actuator (9) in fluid communication.
