A position controller capable of controlling the depth or lateral position of a towed array. The position controller comprises a tubular fuselage from which a pair of wings may be extended over a range of sweep angles between fully open and stowed positions. In fully or partly open positions, two wings present a positive angle of attack relative to the axis of the fuselage. In the stowed position, the wings are fully retracted into a wing receptacle within the fuselage for unfettered passage into and out of a submarine on the array deployment and retrieval handling system. The sweep angles of the two wings are independently adjustable by first and second actuators.

L'invention concerne un contrôleur de position pouvant contrôler la profondeur ou la position latérale d'un réseau remorqué. Le contrôleur de position comprend un fuselage tubulaire à partir duquel une paire d'ailes peut s'étendre sur une plage d'angles de flèche entre des positions totalement ouverte et repliée. Dans les positions totalement ou partiellement ouvertes, deux ailes présentent un angle d'attaque positif relativement à l'axe du fuselage. Dans la position repliée, les ailes sont totalement rétractées dans un réceptacle d'ailes à l'intérieur du fuselage pour le passage sans entraves dans et hors d'un sous-marin sur le système de gestion de déploiement et de récupération du réseau.
