Abstract

L’invention concerne un dispositif (136) de commande d’un système (124) de transfert de puissance entre un arbre haute pression (108) et un arbre basse pression (116) d’une turbomachine (104) d’un aéronef (102), comportant : - un module d’analyse de fatigue (142) de la turbomachine (104) conçu pour déterminer, parmi deux indicateurs (D1, D2) mesurant respectivement deux fatigues de la turbomachine (104) et augmentant avec respectivement deux paramètres (NHP, T45) de fonctionnement de la turbomachine (104), celui qui est en avance c’est-à-dire qui risque d’atteindre en premier un plafond de fatigue respectif (D1max, D2max) ; - un module d’analyse de fonctionnement (144) de la turbomachine (104) conçu pour détecter lorsqu’un plafond de fonctionnement (NHPmax, T45max) est atteint par le paramètre (NHP, T45) associé à l’indicateur (D1, D2) en avance ; et - un module (140) de commande du système de transfert de puissance (124), conçu, en réponse à la détection, pour commander le système de transfert de puissance (124) en maintenant à ce plafond de fonctionnement le paramètre (NHP, T45) associé à l’indicateur (D1, D2) en avance tout en laissant augmenter l’autre paramètre (NHP, T45), de manière à augmenter une marge de puissance de sortie de la turbomachine (104).
