Title
(EN) DEVICE FOR CONTROLLING AN AIRCRAFT ENGINE COMPRISING TWO REDUNDANT CONTROL CHANNELS
(FR) DISPOSITIF DE COMMANDE D'UN MOTEUR D'UN AÉRONEF COMPRENANT DEUX VOIES DE COMMANDE REDONDÉES
Abstract
(EN)
The invention relates to an engine control device comprising a first control channel (V1) and a second control channel (V2), each control channel comprising a first sensor (CAV1, CAV2) and a second sensor (CBV2, CBV2), each configured to provide, respectively, a first measurement (A) and a second measurement (B) to each channel, each of the channels having an active or passive state defining an active channel (V1) or a passive channel (V2), the active channel (V1) being designed to control at least one actuator (ACT) of the engine while the passive channel (V2) is designed to take over for the active channel if the latter fails.
(FR)
L'invention concerne un dispositif de commande d'un moteur comprenant une première voie de commande (V1) et une deuxième voie de commande (V2), chaque voie de commande comprenant un premier capteur (CAV1, CAV2) et un second capteur (CBV2, CBV2) chacun configuré pour fournir respectivement une première mesure (A) et une deuxième mesure (B) à chaque voie, chacune des voies comprenant un état actif ou passif définissant une voie active (V1) ou une voie passive(V2), la voie active (V1) étant destinée à piloter au moins un actionneur (ACT) du moteur tandis que la voie passive (V2) est destinée à prendre le relais sur la voie active en cas de défaillance de cette dernière.
