Computational modeling of aeroelastic oscillations of a ring in the subsonic plane-parallel flow

A model problem of aeroelasticity has been studied, where the profile being considered as an elastic ring interacts with a twodimensional flow of incompressible medium. The flow parameters and loadings are calculated using the vortex element method. It is shown that the profile elasticy and its fixing conditions have a significant influence on the vorticity generation process and parameters of unsteady aerodynamic loads, being polyharmonic.
