Abstract

L’invention concerne un système (20) d’alimentation en carburant d’une turbomachine, comportant un circuit de carburant comprenant une pompe (42) configurée pour envoyer dans ledit circuit de carburant un débit de carburant qui est une fonction croissante de la vitesse de rotation d’un arbre (43) de ladite pompe, et un capteur de débit (46) agencé à une sortie de ladite pompe, caractérisé en ce que ledit système comporte un dispositif d’entrainement (40) comprenant un moteur hydraulique (48) configuré pour entraîner ladite pompe, et en ce que ledit système comporte des moyens de commande (58) comportant une source de puissance hydraulique (60) et étant configurés pour commander ledit dispositif d’entrainement à partir d’une mesure fournie par ledit capteur de débit de manière à adapter la vitesse de rotation de l’arbre de ladite pompe pour respecter une consigne de débit de carburant en sortie dudit circuit de carburant.
