Abstract

Within this work, 2D simulations are used to assess the potential of variable camber (VC) to increase the effectiveness in terms of buffet onset delay of shock control bumps on the airfoil of a HLFC wing. Since the bumps are restricted to the spoiler, positioning of the bump relative to the shock is not ideal, which limits the potential in shifting the transonic buffet boundary to higher cL. VC is used to move the shock towards the leading edge. This increases the capabilities of shock control bumps in moving buffet onset to higher cL values over a wide range of bump crest positions and bump heights. In addition, VC enables the usage of a structurally designed bump on a morphing spoiler, which is optimized for wave drag reduction without VC and can be used for buffet onset delay with VC applied.
