Description

Variable wing hydrofoil

Technical Field

The utility model belongs to the technical field of boats and ships, especially, relate to a variable wing hydrofoil.

Background

The hydrofoils in the existing main stream hydrofoil catamaran are fixed wings which are vertically placed and vertically folded. The principle of the hydrofoil is derived from the upper round and lower flat model of the airplane wing, when air passes through the wing, the air flow speed passing through the upper edge of the wing is faster than the air flow speed passing through the lower edge, the air pressure of the lower edge is generated to be larger than the air pressure of the upper edge, namely, the pressure difference, and the air has upward lifting force on the wing, so that the airplane can be lifted off. The principle of hydrofoils is also the same, so that hydrofoil sails can fly above the water surface off the water surface. F50, M32, Nocardia, etc. all belong to fixed hydrofoil catamarans. The fixed wing hydrofoil is passively retracted above and below the water surface, and lifting and settlement are realized by means of the unidirectional lifting force generated by the hydrofoil shape, so that the downward pressure cannot be generated. The consequence of the unidirectional control which only can be lifted and can not be lowered is that the high gravity center which is high originally can not be offset, and the fixed hydrofoil sailing boat which only floats on water often has a boat-turning accident in the competition, or the shallot is planted in a reverse way or turned on one side.
