The wing spar is modelled as a cantilever beam that is free at the end, the end that is free is at co-ordinates (0, 0) in diagram 2. Thus, the wing design begins with one known variable (S), and considering all design requirements, other fifteen wing parameters are obtained. 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. Some of the forces acting on a wing spar are Upward bending loads resulting from the wing lift force that supports the fuselage in flight. The report nally ends with pictures of the current design. 4, Case 3. In order to obtain efficient designs for future aircrafts with respect to requirements like aerodynamics, structure and cost performance, Multidisciplinary Design Optimization (MDO) is a key factor (Sobieszczanski-Sobieski and Haftka, 1997) due to several reasons.

Each of these components act like a beam and torsion member as a whole. MATLAB MuPAD software was used to derive analytical models for the aircraft wing loads using The shear force here starts at 0 as there are no reaction forces here and there are no loads acting at this point. A six seater transport aircraft wing spar design is considered and the initial design has been carried out using conventional design approach which was found out to be with heavy weight. Although the spar shapes in Figure 8 are typical, actual wing spar configurations assume many forms.
