Design Life Estimation of Commercial Aircraft Wing through Structural and Aerodynamic Analysis at various Altitudes and Angles of Attack

Dildar Ahmed and Ali Javed*

Design life estimation has been a reason of concern in design of commercial aircraft wings since it incorporates the study of various parameters that are interconnected. This study focusses on the aerodynamic and structural analysis of Airbus A320 wing at various Mach numbers and angles of attack. Aerodynamic pressure loads are calculated by performing CFD (Computational Fluid Dynamics) on the skin surface of wing. CFD loads are then transfer to the internal structural components of wing (ribs, spars) for structural analysis. The study gives estimates of stresses and deformations on internal structural members against aerodynamic loads and identified stress concentration areas which will subsequently be used for determining the remaining life of aircraft wing and structural behavior at different angles of attack.
