FIELD: engine manufacture. SUBSTANCE: jet engine incorporates a container with evaporating fluid to be injected into combustion chamber. In a liquid fuel version the fluid is kept in a special tank communicating with a pump rotated by the turbine of the common turbine pumping plant while discharge of said pump communicates with the combustion chamber. In the solid fuel version of the jet engine the fluid is contained either in central block (multinozzle version) or in the cavity between the external jacket and engine (single-nozzle version). The upper part of said cavity communicates with upper part of engine frame while its lower part, with nozzle of combustion chamber. EFFECT: reliability enhanced by lower thermomechanical loading of engine structure and by fixing ecologically harmful components. 6 cl, 4 dwg
