ABSTRACT A wing is a type of fin with a surface that produces aerodynamic force for flight or propulsion through the atmosphere, or through another gaseous or liquid fluid. As such, wings have an airfoil shape, a streamlined cross-sectional shape producing lift. A wing's aerodynamic quality is expressed as its lift-to-drag ratio. The lift a wing generates at a given speed and angle of attack can be one to two orders of magnitude greater than the total drag on the wing. A high lift-to-drag ratio requires a significantly smaller thrust to propel the wings through the air at sufficient lift. The requirements for the aircraft wing are High stiffness, High strength, High toughness and Low weight. In design and finite element analysis of aircraft wing is designed and modeled in 3D modeling software CREO. The wing is modified by three major planform geometries relating to taper ratio are rectangular, trapezoidal and delta shape in order to increase the strength of the wing. The materials used for aircraft wings are mostly metallic alloys. In this thesis, the materials are replaced by composite materials S Glass and Kevlar 49. Static analysis is done to determine the stresses produced by applying loads. Modal analysis is done on the aircraft wing to determine the frequencies and deformations, stress due to frequencies. Fatigue analysis to estimate the life of the wing. Analysis is done in ANSYS
