This paper presents an overview of the work performed recently at ONERA on the control of the buffet phenomenon. This aerodynamic instability induces strong wall pressure fluctuations and as such limits aircraft envelope; consequently, it is interest

This paper is a review on the dynamics of vortices in fluids which get involved in aircraft wakes. Basic notions useful to appraise their dynamics are: inertial waves, 3D instabilities due to vortex interaction, vortex merging, vortex breakdown and t
