Abstract: In this study, layering of all components of lambda wing including spars, shell and ribs is performed in initial dimensions and sizes using manual calculations. Then, strength analysis and buckling of structure are performed using finite element method. To remove flexural-tensile and flexural-torsional effects in wing structure, the layering is considered in symmetric mode. Moreover, continuity of integrated structures is observed while initial designation. For geometric modeling, Catia Software is used and for stress-strain analysis and types of buckling such as Euler and Crippling buckling, Nastaran Software is used due to boundary conditions. Finally, critical points of the structure against types of analysis are detected and are redesigned if required.
