The optimal shape of the airfoil generates high lift and low drag within the design constraints often imposed by the structural requirements. In the present study, the optimization of airfoil shape is carried out using genetic algorithm, particle swarm optimization methods for a typical airfoil NACA4412 in MATLAB environment. Airfoil parameterization is done using cubic spline, PARSEC and CST methods. Panel method based flow solver XFOIL is used as flow solver for optimization. Flow simulation of airfoil is also carried out on CFD software ANSYS FLUENT. The optimization is carried out for maximum lift and minimum drag.

Commercial aircraft flooring is about 1cm thick, 2ft by 4ft in size and is made of glass or carbon fiber reinforced epoxy skins with a nomex honeycomb core. The use of sandwich construction, is efficiently the most structurally efficient component. The substitution of Advanced Grid Stiffened (AGS) structures is not required in reducing structural weight, but at reducing cost factor. Advanced structures are characterized by a lattice of rigid, interconnected ribs, which proves to be a highly efficient design. AGS structures also offer other inherent advantages such as high impact resistance, when damaged, delamination and crack propagation tend to remain isolated to a cell. Commercial aircraft floors are designed to withstand high compression loads. The project deals with Design and Analysis of a flat panel of sizes 410mm X 410mm with an orthogonal grid, 4 longitudinal and 4 transverse stiffeners of 10mm width and 14mm height has been considered. The flat panel has been designed and structural analysis is carried out by using ANSYS Software for two different types of materials (Carbon/epoxy, glass/epoxy).
