DRIVE SYSTEM TO INCREASE LIFT AT WING LEADING EDGE Russian patent published in 2013 - IPC B64C9/24 

FIELD: transport.

SUBSTANCE: invention relates to aircraft engineering, particularly, to aircraft aerofoil. Proposed drive system comprises tie rod 4 coupled with wing at first pivot point 3 and lift augmenter 1 at second pivot point 7, first drive mechanism 5 to drive augmenter 1 around first pivot point 3 and second drive mechanism to turn augmenter 1 about second pivot point 7. Second drive mechanism 8 may be actuated irrespective of said first drive mechanism to create sealing force between augmenter 1 and aircraft wing leading edge 2. Method of actuating lift augmenter 1 at wing leading edge 2 using aforesaid system comprises turning augmenter 1 about pivot point 3 by drive mechanism 5 and downward about leading edge from retracted position into mid position, turning said element 1 around point 7 by second drive mechanism 8 to displace augmenter 1 into extended position. Note here that second drive 8 creates sealing force in retracted and mid positions of element.

EFFECT: complex displacement of element 1.
