PCT No. PCT/FR97/00263 Sec. 371 Date Aug. 13, 1998 Sec. 102(e) Date Aug. 13, 1998 PCT Filed Feb. 11, 1997 PCT Pub. No. WO97/30361 PCT Pub. Date Aug. 21, 1997A method for controlling the navigation of a towed linear acoustic antenna. Birds equipped with variable-incidence wings are fixed onto the antenna. Through a differential action, the wings allow the birds to be turned about the longitudinal axis of the antenna so that a hydrodynamic force oriented in any given direction about the longitudinal axis of the antenna is obtained. Power and control signals are transmitted between the antenna and the bird by rotary transformers. The bird is fixed to the antenna by a bore closed by a cover. The bird can be detached automatically as the antenna is raised so that the antenna can be wound freely onto a drum. This method allows the full control of the deformation, immersion and heading of the antenna.
