Modal approaches are often preferred to the wave-based ones for the evaluation of instability conditions in classical nonlifting aeroelasticity of plates and shells. Here, within a wave-based finite element framework, sub- and supersonic aerodynamic models are introduced to analyze the effect of self-excited aerodynamic loading terms on the dispersive characteristics of structural waves. The method is validated by using a specific literature test case and is applicable on both isotropic and multilayered flat and curved structures. The sound transmission is also computed under sub- and supersonic turbulent boundary-layer excitations: the effect of including or neglecting the aeroelastic coupling is discussed.
