OPENING RIGID WING

摘要

A rigid wing sail fitted to a water-borne vessel. The rigid wing sail includes a pair of elongate rigid panels, and a hinge element designated generally as coupled to the panels to permit pivotal movement of the panels relative to one another. Each of the pair of panels includes an adjoining edge and an opposing lateral edge. The hinge element is coupled to the panels at the respective adjoining edges to form either a closed configuration of the wing with lateral edges of respective panels positioned adjacent one another wherein the rigid wing sail is closed or an open configuration of the wing with the lateral edges of the respective panels separated from one another wherein the rigid wing sail is set at a variable camber.
