wingIntermediateStructureCellType

Between the upper and the lower shell the wing is filled with a material, e.g. with a honeycomb core described by its smeared properties.

The region is bounded like a cell of a shell: a border at its leading and one at its trailing edge (cellPositioningChordwiseType) and one at its inner and one at its outer end (cellPositioningSpanwiseType). Each of them is given by relative coordinates, by a spar or by a rib, and the corners of the region are the points where the borders meet.

rotZ turns the material in the plane of the chord surface. It is measured like the angle of the stringers and the orthotropy direction of the skin, from the straight line through the leading edge points of the first and the last element of the component segment (see wingStringerType). rotX turns it about the x axis of the wing, and 0 keeps it in the chord surface.

Section through a wing between its front and rear spar: the skin of the upper and the lower shell, the filling between the two shells, and the opening that a cut-out leaves in the lower shell between the relative chordwise positions 0.4 and 0.55

The figure shows the filling in a section of the example, between the two spars and the two shells.

Example

One filled bay of the example, between the two spars and between two ribs of the outer rib set:
