DESCRIZIONE
It is proposed a wing releasing system for releasing at least one wing (12c) of a set of wing or wings of a navigation control device (40), the navigation control device being adapted for controlling the depth and/or the lateral position of a towed acoustic linear antenna (20a) and comprising a body (11) to which is attached the set of wing or wings. The wing releasing system comprises: a releasing decision circuit (44), for generating a release request signal when detecting that a foreign object is caught by at least one wing of the set of wing or wings; and an actuator (50) comprised in the navigation control device, for releasing from the body the at least one wing of the set of wing or wings, when receiving the release request signal.
