Leading-edge

Leading-edge Radiator: A radiator built into the leading edge of a mainplane.
Leading Sweep: As applied to a propeller blade, a general curvature of the blade towards the leading edge.

LEADING-EDGE - The edge of an airfoil which first meets the airstream in normal flight.

LIFT - The force generated by an airfoil section, acting at right angles to the airstream flowing past it ...

The use of plywood leading-edge covering presents a problem in the attachment of fabric since stringing (ie, the through-wing stitching normally used) would be required to stop at the plywood-covered surface.

In 1895, he tested unsuccessfully a leading-edge flap device that was intended to counteract air pressure on the cambered upper surfaces of the wings as well as steering air-brakes and a form of wing-warping.

Minor features include wing fences, leading-edge dog teeth, vortex generators, blisters, pylons, winglets and wingtip pods. These are not usually considered significant to the wing configuration.

Leading edge flap - a portion of the leading edge of an airplane wing which folds downward to increase the camber of the wing to increase both its lift and drag. Leading-edge flaps are extended for takeoffs and landings to increase the amount of ...

higher lift coefficient, many airplanes are equipped with flaps (on the wing trailing edge), and a few designs use slats (on the wing leading edge) to further lower the stall speed. The following diagram illustrates the use of flaps and leading-edge ...

The answer is that it spent a lot of time hanging around near the leading-edge stagnation line, moving much slower than the ambient air. Then as it passes the wing, it moves faster than ambient, but not faster enough to make up for the lost time.
