Abstract
(EN)
A fin control assembly (26) includes a housing (42), an arm (44) configured to couple to a fin and to steer the fin relative to the housing, and a locking member (46) disposed within the housing. The locking member is configured to (i) lock the arm in a substantially fixed state to inhibit movement of the arm relative to the housing when the locking member is in an engaged position, and (ii) unlock the arm from the substantially fixed state to allow the arm to steer the fin relative to the housing when the locking member moves from the engaged position to a disengaged position. The locking member has a cylindrical body portion (72) and a cylindrical end portion, which is eccentric with the cylindrical body portion, to enable the locking member to lock the arm in the substantially fixed state while the arm holds the fin in a neutral location.

Un ensemble de commande d'ailette comprend un corps, une patte configurée pour se coupler à une ailette et pour diriger l'ailette par rapport au corps et un élément de verrouillage situé dans le corps. L'élément de verrouillage est configuré pour (i) verrouiller la patte dans un état sensiblement fixe afin d'empêcher le mouvement de la patte par rapport au corps lorsque l'élément de verrouillage se trouve en position bloquée et (ii) déverrouiller la patte et la libérer de son état sensiblement fixe pour permettre à la patte de diriger l'ailette par rapport au corps lorsque l'élément de verrouillage passe de la position bloquée à une position libérée. L'élément de verrouillage comporte une partie d'enveloppe cylindrique et une partie terminale cylindrique qui est excentrique par rapport à la partie d'enveloppe cylindrique pour permettre à l'élément de verrouillage de verrouiller la patte dans l'état sensiblement fixe alors que la patte retient l'ailette dans une position neutre.
