| Abstract: | Results are presented of an experimental investigation of the interaction between a supersonic underexpanded jet and an obstacle mounted at various distances from the nozzle exit. It is shown that for certain distances h unstable modes of flow around the obstacle are observed for Ma=2.18, n=1.9, 3.6
