Abstract

L'invention propose une turbomachine à engrenages comportant une soufflante (16), un arbre basse pression (28) qui entraine la soufflante (16) en rotation autour de l'axe principal (A) de la turbomachine (10), un réducteur (40) de vitesse interposé entre la soufflante (16) et l'arbre basse pression (28), et un alternateur (52) entrainé notamment par l'arbre basse pression (28), caractérisée en ce que l'alternateur (52) comporte un inducteur (54) et un induit (56) dont l'un de l'inducteur (54) et de l'induit (56) est solidaire de la soufflante (16) et l'autre de l'inducteur (54) et de l'induit (56) est solidaire de l'arbre basse pression (28).
