WingSection type, containing a wing section. The sections contains elements, where the airfoils are defined. For the definition of a wing at least two sections (root and tip) have to be defined, but any number greater than 2 is also possible.

Mathematically spoken a section is a coordinate system that is translated, rotated and scaled relative to the wing coordinate system. This transformation parameters are defined withing the transformation section.

In addition to the translation, which is defined in the transformation part, the section can be translated by using the positionings vectors (wing->positiongs). Translation of the positionings vectors is added to the translation of the section.

An example for wing sections can be found in the picture below:
