ABSTRACT:
The member may for instance be a sail having at least one opening to create an air flow from the pressure face to the suction face, and guides to guide the air emerging from the opening on the suction face side and direct it tangentially in relation to the member. The opening and the guides are formed temporarily and adjusted by varying the position and/or geometry of at least one portion and/or region of the device. The device further includes devices for adjusting the member's geometry, including the shape and concavity of its camber.
