Abstract

This work presents experimental studies on fluid/structure interaction in supersonic flows, performed in the test sections TMK and L3K of the German Aerospace Center in Cologne. The generic model for the investigation of the mechanical aspect is an elastic panel clamped at two sides and hit by an oblique shock wave. The flow field is surveyed with schlieren photography, pressure probes and oil-film technique. Displacement sensors and strain gauges measure the panel deflection. The shock wave/boundary layer interaction and the vibration characteristics of the structure are also analysed separately. The thermal aspect is studied with flat and curved panels of fibre-reinforced ceramics in high enthalpy flows. Configurations with and without back plane insulation were tested at two angles of attack. The panel heating is documented with the help of infrared thermography, pyrometers and thermocouples. The analysis includes heat transfer via radiation and catalysis on the surface. The interpretation of the experimental data is supported by simulations conducted with the numerical flow solver TAU and the finite element solver ANSYS® as well as coupled simulations.
