Abstract

L'invention concerne un longeron (82) pour une aube de turbomachine, qui comporte un corps (85) de forme allongée suivant un axe principal (Z) suivant lequel il comporte une première partie (86) configurée pour être à l'intérieur d'une pale de l'aube (58), et une seconde partie (67) configurée pour être à l’extérieur de la pale (62) et pour former un pied (66) de l’aube (58), caractérisé en ce que le corps (85) comporte une cavité (98) qui débouche dans une surface externe (100) de ladite première partie (86) par une ouverture (102), et un bouchon (104) reçu dans la cavité (98) et fermant l'ouverture (102) qui délimite un premier conduit (106) d'un circuit de refroidissement interne (96) qui comporte au moins un deuxième conduit (108) qui traverse au moins la deuxième partie (67) et qui débouche à l'extérieur de la deuxième partie (67).
