Submerged object suspended from a towing cable optimized to neutralize disrupting hydrodynamic forces

An object intended to be towed in a fluid by a cable along a substantially horizontal transport axis;

• the object comprising a single-shell monocoque body and at least one fixing arm, the body being intended to be suspended under the effect of gravity from the cable by means of said at least one fixing arm,
• the object wherein the body comprises:
• an exterior hydrodynamic surface that is symmetric with respect to a vertical plane containing the transport axis so as to limit the lateral lift of the body,
• a central opening passing through the body along a vertical axis, which opening is intended to be occupied by the fluid so as to equalize the pressures of fluid flowing along the exterior surface, so as to limit the vertical lift of the body;
• making it possible to limit the hydrodynamic forces that may be generated perpendicular to the transport axis by the flow of fluid around the body and that are liable to lead to a load in rotation about the transport axis by opposing the effect of gravity.
