Abstract
Disturbance level measurements are carried out in the Hypersonic Ludwieg Tube Braunschweig (HLB) at \(\text{ Ma } = 5.9\) considering three shapes of stagnation point probes (SPP) and two different types of high speed surface sensors. Navier Stokes mean-flow solutions are produced for the flow around the front shapes to increase the understanding of the dependence of the mean flow on the probe shape. Performed direct numerical simulation (DNS) for one SPP configuration delivers transfer functions as the ratio of incoming disturbance to surface data at the stagnation point. The transfer functions are used for computing the modal decomposition of representative disturbances in the freestream.
