Stringers of a shell or of a cell

All stringers of a shell or of a cell have the same cross section, that of the structural element referenced in <stringerStructureUID>. They are given in one of two ways:

with a <pitch>: one stringer runs through the point given in <refPoint>, the others parallel to it, each one pitch further, measured perpendicular to the stringers;
explicitly with <numberOfStringers>: the stringers are spread between four chordwise borders, their inner ends between <innerBorderXsiLE> and <innerBorderXsiTE>, their outer ends between <outerBorderXsiLE> and <outerBorderXsiTE>. This way the stringers can fan out towards the tip.

<angle> turns the stringers in the surface. It is measured from the straight line through the leading edge points of the first and the last element of the component segment, about the normal of that surface. <angleReference> replaces that direction by the leading edge, the trailing edge, the y axis of the wing (globalY) or a spar of the structure.

Oblique view of a part of the upper skin of a wing between its leading and its trailing edge, with the traces of the front and the rear spar on it. One stringer, drawn strong, runs through the reference point; the others follow at the pitch from it, which is marked between two of them. All of them are turned by the stringer angle of 8 degrees from the reference direction, the line through the leading edge points of the first and the last element of the component segment

The figure shows a part of the upper skin of the example with its stringers: one of them runs through the reference point, the others at the pitch from it, all turned by the angle from the reference direction.
