The present invention is directed generally toward leading edge flap
apparatuses and corresponding methods. One aspect of the invention is
directed toward an aircraft system having an airfoil, an actuator driver,
and a leading edge device with two flow surfaces and six links. In a
further aspect of the invention, the flow surfaces of the leading edge
device are at least approximately located in the same position when the
actuator driver is in two different positions. Another aspect of the
invention is directed toward an aircraft system having an airfoil and a
leading edge device movable between at least a retracted position and an
extended position along a motion path having two segments. The second
flow surface can be positioned generally behind and/or generally above
the first flow surface when the first and second flow surfaces are
located in the first segment of the motion path.
