The wing of an aircraft is the most critical part of an aircraft structure as it greatly influences the aerodynamic performance of the aircraft. Maintaining aircraft stability involves a lot of factors including the control of vibrations in an aircraft wing. It is paramount that the structural integrity of the aircraft body and the wing is maintained to avoid structural failure. The interaction of aerodynamic forces and elastic forces in a structure leads to aeroelasticity problems and the most important dynamic aeroelastic problem is Flutter. Flutter is a dynamic, oscillatory structural instability enabled by interactions between unsteady aerodynamic forces and moments created by vibratory motion of lifting surfaces and the vehicles to which these surfaces are attached. In this paper, an aircraft wing is designed and modeled using CATIA whose material is Aluminium Alloy. The vibrational analysis is carried out using Modal analysis in ANSYS Workbench to determine the bending modes and torsional modes of the wing which gives us the mode shapes of the classical flutter of the chosen wing.
