Kurzfassung
This paper presents the results of transition experiments with a 3° half angle cone at Mach 6. The transition position was measured with an infrared camera and simultaneously the pressure fluctuations in the boundary layer with high speed pressure sensors. A segment with regular micro pores causes a measurable damping of the pressure fluctuations in the boundary layer (Mack modes) but no transition delay. In addition the influence of the nose radius, of the unit Reynolds number and of the free stream temperature on the transition as well as the pressure fluctuations is investigated.
