Abstract

L'invention concerne un circuit (CL) d'huile de lubrification d'une turbomachine, le circuit (CL) comportant une vanne (V) de répartition configurée pour répartir, en fonction d'un signal (COM) de commande de répartition de débit d'huile, un débit d'huile entre un échangeur (ECH1) de chaleur positionné en contact avec un flux secondaire de gaz de la turbomachine pour y refroidir l'huile et un conduit (DER) de dérivation, reliés à un conduit (CEq) d'huile, relié à un échangeur (ECH2) de chaleur positionné contre une conduite de carburant de turbomachine pour y refroidir l'huile. L'invention est caractérisée en ce que le circuit (CL) d'huile comporte un compartiment (RGB) d'engrenages d'un réducteur (44) de rotation configuré pour abaisser une vitesse de rotation d'un arbre de soufflante par rapport à une vitesse de rotation d'un arbre de compresseur basse pression ou de turbine basse pression, un conduit (Crgb) d'huile entre l'échangeur (ECH2) et le compartiment (RGB), et un dispositif (REG) de régulation pour réguler une deuxième température (Trgb) d'huile du conduit (Crgb) sur une consigne (Trgb_ref) de température, comportant : - une boucle locale (BL) de régulation, configurée pour générer le signal (COM) de commande de répartition de débit d'huile et réguler une température (Teq) d'huile du conduit (CEq) sur une consigne (Teq_ref) de température, - une boucle globale (BG) de régulation, configurée pour générer la consigne (Teq_ref) en fonction de la température (Trgb) et de la consigne (Trgb_ref).
