The ribs gives the proper aerodynamic shape to the wing. And spar will take most of the bending loads in wing structure. In the present work ribs, spars and wing structure is optimized for twisting, bending and axial loads in terms of size and shape for a particular 10 seater aircraft. CFRP is considered for the material configuration of the wing. Cruise load is considered for the analysis of the wing. Design has been made using Catia V5 R21 and Analysis has been carried out using ANSYS 14.5 workbench. The results are validated using standard design of the 10 seater Cessna 402 aircraft.
