Micro Abstract:
Turbulent wake flows of generic Ariane 5-like space launcher configurations are investigated using zonal turbulence modeling and reduced-order methods. For two selected, dynamically crucial trajectory stages, i.e., $M_\infty = 0.8$ and $M_\infty = 6$, previously unknown coherent three-dimensional modes are extracted and attributed to the single characteristic frequencies and wave lengths which are responsible for critical side loads on the nozzle structure.
