WAVE PROPELLER Russian patent published in 2000 - IPC

FIELD: shipbuilding; propellers employing wave energy for motion of ships. SUBSTANCE: wave propeller is provided with submersible swivel tractive hydrofoil articulated on strut secured on horizontal shaft which is located in parallel with ship's CL. Marine wave propeller is additionally provided with unbalanced control hydrofoil which is also articulated on strut. Wave propeller is also provided with kinematic gear train at gear ratio equal to one which is mounted between tractive and control hydrofoils. Swivel axle tractive hydrofoil runs through construction center of lateral pressure. Angle between center hydrodynamic chords of tractive and control hydrofoils is not equal to zero. Tractive hydrofoil has off center profile and convex-concave form in longitudinal section. EFFECT: enhanced efficiency of using sea waves for motion of ships. 2 dwg
