Buffet Active Control - Experimental and Numerical Results

Abstract

The study aims are the active control of transonic buffet over airfoils and wings. A new moving device at the trailing-edge, a so-called. "Trailing Edge Deflector" (TED) designed at ONERA, is used to decrease the buffet instabilities. This study is limited to buffet phenomenon on upper surface of a stiff 2D airfoil in transonic flow. Experimental and numerical results allow to better understand the phenomena and to validate the efficiency of the TED
