STRUCTURAL ANALYSIS OF WING SKIN MADE UP OF DIFFERENT TYPES OF COMPOSITES

Abstract

A wing is the most crucial part of any flying machine. It creates a lift due to the momentum phenomenon as air molecules are suppressed down by the aerofoil shape. So, in reaction, air molecules apply some force which has two components that can be resolved in two components one is drag and the other one is lifted. Wing mainly consists of three parts skin, spars, and Ribs. In the design of the wing, I consider 15 ribs and two spars. Front spars are made up of an I section, and the back part is of a C section running longitudinally along the length of the wing. This study aims to apply different composite materials to wing skin e.g. Epoxy- carbon is woven, epoxy carbon UD, and Epoxy E-glass, and compare their results in FEA analysis, and gets the best material for wing skin. The initial wing has been modeled in the Catia by taking coordinates of NACA 4412 from the NASA website and then performing structural analysis to get deformation and stresses with different speeds. The best material for wing skin has been identified by structural analysis of different types of composites and Epoxy – Carbon UD has been found as the best material for an aircraft wing.
