Abstract

Procédé de commande d’une vanne de pilotage de jeux lors d’une montée étagée en phase de croisière Procédé de commande d’une vanne de pilotage de jeux (18) d’une turbomachine dans lequel, lors d’une manœuvre d’augmentation de régime moteur en phase de croisière, une commande de réduction d’ouverture de la vanne de pilotage de jeux (18) est actionnée par un calculateur de régulation moteur à pleine autorité (22) sur la base d’un changement d’état d’un signal de montée étagée (SCs) fourni par un système de management de vol (20) afin d’augmenter les jeux en sommet d’aubes (120, 122) de la turbomachine. Figure pour l’abrégé : Fig. 1.
