(�� Software packages are to be used to design an aircraft wing spar structure and Finite Element Method (FEM) also be used to calculate the stresses developed at each station for a given bending moment. 4, Case 3. The key element of the wing consists of a pressurized telescopic spar that can undergo large-scale spanwise changes while supporting wing loadings in excess of 15 lbs/ft. When designing the wing, other wing parameters are determ­ ined. (�� This paper discusses the design, development and testing of an inflatable telescopic wing that permits a change in the aspect ratio while simultaneously supporting structural wing loads. For example, when designing a wing it is necessary for this wing to have the maximum lift-to-drag ratio, the minimum weight, the sufficient lifespan and enough internal volume to contain the large amount of fuel, to be easy to manufacture and etc. The wing must produce sufficient lift while generate minimum drag, and minimum pitching moment.
