Kurzfassung
The wake flow field of a generic rocket launcher geometry at Mach 0.8, with a supersonic exhaust jet at stagnation conditions from 288 to 919 K was analyzed regarding its spectral content by means of highspeed Schlieren imaging and pressure measurements. The spectral analysis captured typical wake flow frequencies and their characteristic mode shape for the cross-flapping and swinging motion of the ambient shear layer at SrD = 0.19 and 0.35. At certain conditions, a strong amplification of the swinging motion was observed, which is probably governed by a coupling of the dynamic wake flow modes and the acoustic chamber properties.
