Abstract

L’invention concerne une aube (17) pour turbomachine d’aéronef, comprenant une pale (18) s’étendant suivant un axe d’envergure (AX) et incluant une pluralité de trous (31, 34) formant un réseau de trous communicants dans celle-ci, cette pale étant équipée de tiges (38) rapportées dans tout ou partie des trous (31, 34) pour délimiter, conjointement avec les trous (31, 34), un circuit de propagation fluidique (X) interne, les trous équipés d’au moins une tige (38) étant formés débouchants sur l’extérieur de la pale, chaque tige (38) comprenant une alternance de portions (41, 42) prévues pour sélectivement autoriser ou bloquer un passage fluide : - le long d’une partie du trou dans laquelle la portion est logée, et/ou - vers un autre trou croisant le trou équipé de la portion, au niveau de leur intersection. Figure pour l’abrégé : Figure 5
