Popis: This paper proposes a new parametrization of very flexible aircraft structural elements to support geometric control studies. First, a sum of basis functions is used to calculate the torsion and curvature distributions of a beam-like structural element. Secondly, the modal functions are used to determine the attitude on SO(3) and the position of each point on the element, assuming constant curvatures. Finally, a simulator implementation of the method is described, along with numerical simplifying strategies.
