Abstract

The design of realistic shock control bumps requires multiple disciplines. In this paper, several shapes of shock control bumps are investigated numerically and evaluated under structural considerations due to constraints imposed by a realistic morphing spoiler structure. The bumps are optimized to reduce the drag of two-dimensional airfoils at a given lift coefficient. The shapes are not only evaluated by their drag reduction potential but also by their structural feasibility. The aerodynamic optimization is done with surrogate based modeling with up to five parameters. It is shown that up to 30% of drag reduction is reached. The penalty of only allowing structurally feasible bump shapes is within an acceptable range of only few percentage points.
