Abstract
La présente invention concerne une aube (1) de turbomachine à calage ajustable, comprenant :un pivot (2) configuré pour être monté en rotation à l’intérieur d’une cavité d’un disque (10a, 10b) de turbomachine de sorte que le pivot (2) soit mobile en rotation par rapport au disque (10a, 10b) autour d’un axe d’empilement (A) de l’aube (1) ;une pale (3) comprenant un pied de pale (30) et fixée au pivot (2) au niveau du pied de pale (30), la pale (3) comprenant une pluralité de sections de pale empilées à partir du pied de pale (30) le long de l’axe d’empilement (A) ;un câble (4a) de connexion électrique comprenant une première partie (4a-1) de câble fixée à la pale (3) et une deuxième partie (4a-2) de câble fixée au pivot (2) et s’étendant entre la première partie (4a-1) de câble et la deuxième partie (4a-2) de câble. Figure pour l’abrégé : Figure 2The present invention relates to a turbine engine blade (1) with adjustable pitch, comprising:a pivot (2) configured to be rotatably mounted inside a cavity of a turbine engine disc (10a, 10b) so that the pivot (2) is rotatable relative to the disk (10a, 10b) around a stacking axis (A) of the blade (1);a blade (3) comprising a blade root (30) and attached to the pivot (2) at the blade root (30), the blade (3) comprising a plurality of blade sections stacked from the blade root (30) along the stacking axis (A );an electrical connection cable (4a) comprising a first cable part (4a-1) fixed to the blade (3) and a second cable part (4a-2) fixed to the pivot (2) and extending between the first cable part (4a-1) and the second cable part (4a-2).
