Experimental results of investigations of an interaction of a single jet with an opposing supersonic flow in the presence of a circular flat plate are presented. The tests have been performed at the free stream Mach number Moo = 1.99 and the following jet parameters: the nozzle exit Mach number Mj = 4.3, relative stagnation pressure of a jet (the interaction parameter) N = 1-1389.9. The jet expansion ratio in tests varied from n < 1 to n = 34.8. The wave structures and stagnation pressure fields near jet were investigated. The reference zones and flow regimes of interaction of a jet with opposing airflow were detected. It was established, that the value of a total pressure coefficient in these zones depended on the interaction parameter N at fixed values of the Mach numbers Moo, Mj and nozzle source geometrical parameter D = DM / dj. It was shown that the drag of a circular flat plate with a jet could be increased in comparison with the drag of an isolated plate.
