Abstract
The present disclosure provides generally for a hydrofoil system that may allow a surfboard to glide above the water surface. According to the present disclosure, a rider may be able to manipulate a hydrofoil device attached to a surfboard with limited training and athletic ability. The present disclosure provides for a hydrofoil system that may allow riders to use a light leaning motion to adjust the angle of a front wing to create forward thrust to produce a flow for creating lift. In some aspects, the front wing may tilt to reduce downward drag force in a lifting phase while locking into place during a glide to provide a sustained lift of the paddleboard out of the water.
Claims20
A hydrofoil device comprising:
- a front wing comprising:
- a convex upper surface,
- a concave lower surface,
- a front wing curved leading edge;
- a back wing comprising:
- an upper surface,
- a lower surface,
- a back wing curved leading edge;
- a fuselage comprising:
- an elongate body with a recess on a forward portion of the elongate body, wherein the front wing fits within the recess and is connected to a forward portion of the elongate body within the recess and the back wing is connected to an aft portion of the elongate body,
- a front hinge connecting a portion of one or both the convex upper surface and the front wing curved leading edge to the recess, wherein the front hinge allows the front wing to pivot within a predefined range;
- and
- a strut connected perpendicular to the elongate body, wherein the strut is connectable to a surfboard.
