Abstract
Technologies are described herein for sailing wing for a vehicle such as a sailboat. As described herein, a sailing wing includes a main sail and a control surface. The control surface is rotatable around a hinge. When deflected, the control surface using force imparted on the control surface by the wind causes the main sail to rotate about a pivot axis, creating thrust.
Claims18
A sailing wing for a vehicle, comprising:
- a main sail extended upwards freely rotatable about a pivot axis;
- a control surface rotatable affixed to a rear portion of the main sail, the control surface rotatable about a hinge to cause a deflection of the main sail about the pivot axis;
- a second control surface rotatably affixed to the rear portion of the main sail, the second control surface rotatable about a second hinge to modify the deflection of the main sail caused by the control surface;
- a controller to modify a position of the control surface;
- and
- a second controller to modify a position of the second control surface, wherein the position of the control surface and the position of the second control surface are individually controllable with respect to each other.

A method of operating a sailboat to adjust for wind angle, comprising the steps of:
- providing:
- a main sail extended upwards freely rotatable about a pivot axis;
- a first control surface rotatably affixed to a rear portion of the main sail, the first control surface rotatable about a hinge to cause a deflection of the main sail about the pivot axis;
- a second control surface affixed to a rear portion of the main sail, the second control surface rotatable about a second hinge to modify the deflection of the main sail caused by the control surface;
- and
- and a controller to individually modify a position of the first control surface and a position of the second control surface;
- and
- individually deflecting the first control surface and second control surface to increase or decrease a thrust of the sailboat.
