  • Bearing structure with reduced tip vortex
    Patent number: 6607168
    Abstract: The bearing structure such as a wing is fitted with toothed platelets (16) at its free edges to break tip vortex produced at these places by fluid pressure distribution. Vortex dissipation is accelerated, vortex remanence is considerably reduced. In the case of a deflector for a line of hydrophones (30) towed by a ship (31) to carry out seismic tests at sea, the noise disturbing the hydrophones (30) is reduced. In the case of marine applications, risks of cavitation are much reduced, particularly with regard to stabilizers or propellers. In the case of aeronautics applications, vortex remanence on take-off and on landing of planes is reduced.
