FIELD: mechanical engineering. SUBSTANCE: flow of working medium enters active nozzle 1 and then passages 6 and 7 through header 5. Flow from passage 6 enters vortex chamber 4 and then comes to inlet of mixing chamber 2 where it ejects passive flow. These flows are mixed in chamber 2 and their velocities are equalizer. Part of active flow from passage 7 is additionally mixed to above-mentioned flow at outlet of chamber 2. Both flows are mixed in diffuser 3 without forming vortices and equalizing the outlet pressure with pressure of surrounding medium. EFFECT: enhanced thrust of jet engine. 2 cl, 2 dwg
