Abstract

A planar expansion-deflection nozzle was tested on the cold flow test bench P6.2 at DLR Lampoldshausen. The comparison between experimental data, design, and numerical results at the design point show a good agreement in general with a slight deviation due to a higher expansion in the experiments. The wake closure was investigated on transient pressure profiles. A hysterisis is existing in these experiments for the transition from open to closed operation mode and back. For low pressure ratios in the off design region, flow separation on the center body was observed. The separation shock interacts with the outer contour leading to pressure peaks.
