Computational analysis for wing geometry optimization

Abstract

In Order to optimize the geometry of aircraft wings,the aim of the work is to highlight the effect of the geometric parameters of these wings such as wing span,chord and camber on the one hand on the behavior of the fluid around the wing and,on the other hand,the behavior of the wing against the forces exerted by the fluid.The tool used in this work is ANSYS software which is highly reputed for its effectiveness in several fields.In the first step of the work we performed the simulation of the air flow around the wing in the fluid part of the software in a three-dimensional configuration.The flow is stationary and compressible with an upstream Mach number of 0.29. This allows us to determine the forces exerted by the fluid on the wing.These forces are represented by the aerodynamic coefficients of lift and drag.In the second part of the work we carried out simulations in the structural part of the software.The wing being subjected to the force exerted by the fluid,we have determined the Von-Mises stress, the elastic deformation, the deformation energy and the maximum deformation undergone by the wing. The simulations were carried out for different configurations corresponding to wings with different wingspans,chords and different camber.The results obtained have clearly shown that the geometrical parameters of the wings have a considerable effect on the evolution of the various variables used
