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.
Claims16
A sailing wing for a vehicle, comprising:
- a main sail extended upwards freely rotatable independent of a direction of the vehicle about a pivot axis;
- a control surface rotatably 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 control surface rotatable about a second hinge, wherein an angle of attack of the main sail and a spanwise distribution of lift of the main sail are determined by the control surface and the second control surface;
- a controller to modify a position of the control surface;
- 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;
- and
- a leading edge control surface separately rotatable from the main sail and rotatable around a leading edge hinge.
