Abstract

FIELD: hydrofoil ships. SUBSTANCE: hydrofoil arrangement of ship consists of fore solid hydrofoil and aft split hydrofoil. Hoisting the hydrofoils from working to upper position is effected through turning around axles secured on hull. Each half of aft hydrofoil is made as yawing forward-swept hydrofoil and fore hydrofoil has sections at ends of span with longitudinal sweepfoward which makes it possible (through use of dihedral shape of these hydrofoils) to ensure stable motion of hydrofoil ship without automatic stabilization and to provide for minium deflection of hydrofoil arrangements from hull lines in upper position without reduction of usable area of deck without impairment of hydrodynamic characteristics hydrofoil arrangement. EFFECT: enhanced efficiency. 3 cl, 13 dwg

Claims (1)

The hydrofoil vessel, the wing-lifting device of which consists of a continuous fore and split aft hydrofoils. The rise of the hydrofoils from the workers to the upper positions is carried out by rotation around the axes fixed on the body. The execution of each half of the stern hydrofoil as a sliding wing with a reverse longitudinal sweep and a bow hydrofoil with sections at the ends of the span and also with negative longitudinal sweep allows, using the positive transverse V-shape of these wings, to ensure both the stability of the SEC without automatic stabilization and minimal deviations of wing devices in the upper position from the rims of the hull without reducing the useful area of the deck and the deterioration of the hydrodynamic characteristics tick of the wing unit.
