Supersonic ejector nozzle loop

The present invention provides a supersonic ejector nozzle loop. The supersonic ejector nozzle loop comprising: a primary flow nozzle, for forming a supersonic flow of primary; secondary flow nozzle, for introducing the secondary stream; mixing chamber disposed downstream of the secondary flow nozzle for mixing a flow outlet end of the inlet end of the secondary flow, the mixing chamber is formed by supersonic lance primary flow and the secondary flow nozzle formed sleeved outer secondary flow nozzle, the inlet end of the mixing chamber is provided with a cap , between the inner wall of the cap is connected to the secondary flow nozzle and the outer peripheral wall of the mixing chamber; test section, the mixing chamber downstream of the adapter; a plurality of primary flow nozzle adapter on the end cap, and to the secondary flow nozzle the central axis of the shaft at circumferentially spaced outer periphery of the secondary flow nozzle. Supersonic Ejector nozzle according to the present invention, the circulation, low processing difficulty, high assembling efficiency.
