Patent ID: 6879542

Claim:
A device for controlling navigation of a towed underwater object, comprising: body equipped with means for fixing the body removably to the object and to allow the device to rotate freely about an axis of the object; a first pair of wings fixed horizontally on the body; first means for modifying an inclination of the first pair of wings to control immersion of the device; a second pair of wings fixed vertically to the body; and second means for modifying an inclination of the second pair of wings to control a horizontal position of the device in a determined situation, wherein the device has zero weight in seawater and distribution of masses fixes a center of gravity of the device below its center of volume to keep the first pair of wings horizontal and the second pair of wings vertical by pendular action, the first and second pair of wings being symmetric with respect to their axis of rotation that is coincident with an axis of the object, and wherein the body is formed of a first hollow part situated above the object, of a second hollow part situated below the object, and of two elongate connecting pieces of a width substantially equal to a diameter of the hollow parts and connecting the hollow parts respectively at their front and rear, and in a middle of which the means for fixing the body removably to the object are fixed.
