The general picture of research in active flow control for aircraft applications has been continuously changing over the last 20 years. Researchers can now obtain design sensitivities by using numerical flow simulations, and new optical experimental

Many flow cases in fluid dynamics face undesirable flow separation due to ad-verse pressure gradients on wall boundaries. This occurs, for example, due togeometrical reasons as in a highly curved turbine-inlet duct or on flow-controlsurfaces such as

The present work describes particle image velocimetry at M = 5.9 in the Hypersonic Ludwieg Tube Braunschweig on a generic space launcher model. The wind tunnel allows high quality flows as well as high repetition rates and, thus, it is suited for PIV
