Title
(EN) METHODS FOR MONITORING SERVICE INTERVAL OF AN ACTUATOR
(FR) PROCÉDÉS DE SURVEILLANCE D'INTERVALLE DE SERVICE D'ACTIONNEUR
Abstract
(EN) A method of determining a service interval for an actuator of a landing gear assembly is suitable for used with a landing gear assembly in which the actuator positions the landing gear assembly between a stowed position and a deployed position. The method includes the steps of determining an actuator travel value for a time interval and increasing a total actuator accumulated travel value by the actuator travel value for the time interval. The method further includes the step of comparing the total actuator accumulated travel value to a predetermined value.
(FR) Un procédé de détermination d'un intervalle de service, destiné à un actionneur d'un ensemble train d'atterrissage, est adapté à être utilisé avec un ensemble train d'atterrissage dans lequel l'actionneur positionne l'ensemble train d'atterrissage entre une position rangée et une position déployée. Le procédé consiste à déterminer une valeur de déplacement de l'actionneur pour un certain intervalle de temps et à augmenter une valeur de déplacement cumulée totale de l'actionneur de la valeur de déplacement de l'actionneur correspondant à l'intervalle de temps. Le procédé consiste en outre à comparer la valeur de déplacement cumulée totale de l'actionneur avec une valeur prédéfinie.
