1. A modular airfoil system, comprising:
at least one sub-element shaped as a section of an airfoil wherein said at least one sub-element is removably attachable to a structure, and wherein said at least one sub-element comprises a upper surface and a lower surface, a first end face and a second end face;
wherein said upper surface and a lower surface together form an airfoil having a cross section;
a plurality of sub-elements selected from the group consisting of a cambered wing sub-element, a modular wing sub-element, and a wing tip; and
wherein each sub-element is removably attached to an adjoining sub-element in an end face to end face connection which the end face of a first sub-element is adjacent to an end face of a second sub-element, and wherein each sub-element is attached to an adjacent sub-element by a connecting sub-element that is removably attached to each sub-element by a stud-recess/dowel-hole connection.
