Fig. 14.11 Uncertainty quantification results for baseline, deterministic optimum, and robust
optimum. Top: Histogram. Bottom: CDF
It can be concluded that a robust configuration (in terms of drag) is effective in
reducing the strength of the normal shockwave while having a larger longitudinal
displacement along the airfoil. Opposite to intuition, the robust configuration does
not fix the shock wave location but spreads it, in order to reduce drag.
The configurations resulting from the deterministic and robust optimization are
shown in Fig. 14.13 together with the baseline RAE2822. In order to avoid the
