SYSTEM FOR UNFOLDING FLYING SAIL IN FORM OF KITE ON WIND DRIVEN WATERBORNE CRAFT Russian patent published in 2009 - IPC B63H9/06 B64C31/06 

FIELD: shipbuilding.

SUBSTANCE: invention relates to wind driven propulsion units. The system for unfolding a freely flying sail (101) in form of a kite on waterborne craft is characterised by that, the sail (101) in form of a kite with the profile of a lifting wing, is joined by a hauling rope (11) to the body of the waterborne craft. The sail (101) can be moved from an initial position on board the waterborne craft to a higher position, free from obstacles at the same or higher level of the launching position. Using an azimuthal rotating holder (181) the sail (101) can be brought into a position, in which it is subjected to sufficient wind effect. The clamping device (181) for detachable connection with the docking adapter of the sail (101) on the side not facing the wind provides for retracting the sail due using automatic holding apparatus.

EFFECT: described is a system for unfolding a sail in form of a kite on wind driven waterborne craft.
