Abstract

The aeroelastic phenomenon plays a critical role in the aerodynamic performance and stability of fixed wing aircrafts. Aeroelastic phenomena may cause flow separation and large deformations of the wing, and implicitly high stresses into the structure. The computational study of aeroelasticity, in high-speed fixed wing, requires fully-coupled aeroelastic algorithms. Therefore, in the present research we propose a CFD based approach using the large-eddy simulation approach along with a finite-element method for the computations of the structural deformations. The analysis is performed for subsonic and transonic flows with Mach number M 0.1 0.3 . The analysis reveals that the elastic deformations of the wing and stresses in the wing increase with the Mach number.
