controlSurfaceBorderLeadingEdgeType

A border is a section of the wing through two points of the chord surface of the component segment: the leading edge point P_LE at etaLE and ξ = 0, i.e. on the leading edge of the wing, and the trailing edge point P_TE at etaTE and xsiTE. etaTE defaults to etaLE. The section plane contains both points and the normal of the component segment. The η and ξ coordinates refer to the parent of the control surface.

Where the rear side of the leading edge device meets the upper and the lower surface of the wing at different positions, xsiTEUpper and xsiTELower replace xsiTE; P_TE then lies at the larger of the two. innerShape describes the hollow rear side between these points (leadingEdgeHollowType), and airfoil replaces the section by an airfoil contour (contourReferenceType). All ξ values, including xsiTEUpper and xsiTELower, are relative chordwise coordinates of the component segment.

Sections at the inner borders of three control surfaces: (a) a flap whose rounded leading edge passes through the nose point at relHeightLE 0.5 and meets the skin at xsiUpperSkin 0.9 and xsiLowerSkin 0.7 of the flap chord from its trailing edge; (b) a slat whose hollow rear side runs from xsiTEUpper 0.15 over the point at xsiTE 0.04 and relHeightTE 0.45 to xsiTELower 0.12; (c) a spoiler between xsiLE 0.55 and xsiTE 0.69 with the lowest point of its leading edge at relHeightLE 0.8

The figure shows the sections at the inner borders of the flap, the slat and the spoiler of the example in controlSurfacesType, with the values that define their contours.
