Abstract

AEROELASTIC INSTABILITY due to fluid-structure interaction is an important phenomenon in aircraft design. In this paper, aeroelastic behavior and FLUTTER instability of an aircraft wing is investigated. For structural simulation, FINITE ELEMENT METHOD, using shell element with non-linear effects, based on large deflection, is applied. For aerodynamic modeling, UNSTEADY PANEL METHOD is employed. The main goal of this study is to add the aeroelastic analysis ability to ANSYS commercial software by developing a computational aerodynamic MATLAB code. Finally, to illustrate the capability of the developed code in handling aeroelastic problems, aeroelastic response of an AGARD 445.6 wing is studied. The results show relatively good agreements with the available experimental data.
