ABSTRACT:
Embodiments of the present invention relate to a linear submersible body including a plurality of rigid segments that are articulated and can adopt relative to one another an orientation making it possible to form a rectilinear body, or a curved body of which the radius of curvature is adapted to the drum of the winch onto which it is wound. The segments are associated with couplers and configured so that a vertical rectilinear posture is naturally obtained when the device is totally submerged and towed by the ship, while the curved posture is obtained naturally by the winding of the device onto the winch. Embodiments of the invention apply to the production of linear and vertical transmitting acoustic antennas.
