Abstract

Un actionneur (100) de turbine à air dynamique (RAT) peut inclure un logement (101) d'actionneur, une tige d'actionneur (103) configurée pour se déplacer par rapport au logement d'actionneur par l'intermédiaire de plusieurs positions, et un premier élément de contrainte (105), un deuxième élément de contrainte (107), et un troisième élément de contrainte (109) positionnés et configurés pour contraindre la tige d'actionneur par rapport au logement d'actionneur. Le premier élément de contrainte contraint la tige d'actionneur à partir d'une première position par l'intermédiaire d'une deuxième position, le deuxième élément de contrainte contraint la tige d'actionneur à partir de la première position par l'intermédiaire d'une troisième position, et le troisième élément de contrainte contraint la tige d'actionneur à partir de la première position par l'intermédiaire d'une quatrième position. Les trois éléments de contrainte peuvent être configurés pour contraindre une turbine à air dynamique contre un crochet de verrouillage en position haute avec une force suffisante pour éliminer des dommages vibratoires au crochet de verrouillage en position haute tout en étant dans la première position.
