Abstract

L'invention concerne un système d'entraînement d'une pompe (1) à carburant d'une turbomachine, la turbomachine comportant un axe moteur et un démarreur (16) ayant aussi fonction de générateur, le système comportant un réducteur (11) à train épicycloïdal comprenant trois éléments, un planétaire (11 A) central, une couronne (11 B) externe et un porte-satellites (11 U) dont les satellites (11 S) s'engrènent avec le planétaire et la couronne, un premier des trois éléments étant destiné à être relié à l'axe moteur (26) et un second des trois éléments étant destiné à être couplé à un arbre de la pompe (1), caractérisé en ce que lesdits trois éléments sont mobiles en rotation autour d'un axe du réducteur, en ce que le système comporte en outre le démarreur (12), ce dernier étant agencé pour entraîner en rotation le troisième desdits éléments du réducteur (11), de manière à modifier un rapport de vitesse de rotation entre le premier et le second desdits éléments. Elle concerne aussi la turbomachine équipée du système et le procédé de régulation de la pompe.
