FIELD: air-jet engines. SUBSTANCE: according to proposed method gas-dynamic circuit of main flow delivered into chamber is formed to provide Mach number of said flow at end of chamber equal to unity, after which main flow is accelerated to supersonic speed at end of divergent part of de-Laval nozzle. Geometry of nozzle circuits of main flow is formed by additional gas flow formed by fuel combustion products and entrained spatially- separated part of main flow. EFFECT: improved dimensional, maneuvering and power characteristics of air-jet engines. 9 cl, 7 dwg
