Aeroelastic Analysis of an Aircraft Wing Type NACA 4412 with Reduced Scale

Zerrouki Halima and Boutchicha Djilali

Abstract—This article addresses the problem of a flutter phenomenon and aeroelastic stability of a typical section airplane wing NACA 4412. The flutter is a dangerous phenomenon which finishes in general by the breaking of the plane, it can be determined as a dynamic instability of the structure. Flutter appears as a result of an interaction of aerodynamic, elastic and inertial forces, it occurs at a determined flight speed which is called the critical speed of the flutter. The objective of our study is to calculate the critical speed of flutter by a numerical simulation using the computer code ANSYS CFX 14.0 then the results are validated by testing with a slice wing on a subsonic wind tunnel. The experimental results are similar to those obtained by the numerical approach.

Index Terms—Aeroelasticity, aerodynamics, ANSYS, critical speed, flutter.
