FIELD: engine engineering. SUBSTANCE: engine has compressor 1 of the inner loop. The outlet of diffuser 2 of the compressor is connected with inlet 3 of the combustion chambers mounted on disk 4 of the working fan inside hollow working blades 5 of the fan. Flame pipe 6 of each chamber is arranged over the span of the working blade of the fan. The outlet of the flame pipe 6 is coupled with the nozzle 7 at the trailing edge of working blade 5. The axis of nozzle 7 is inclined to the plane of rotation of the fan and to the chord of its working blades. Nozzles 7 are provided with a unit for controlling their cross-section and mounted at the top part of blades 5 for permitting rotation about their axes. The outlet of flame pipe 6 is connected with the inlet of nozzle 7 immediately. EFFECT: simplified design and decreased weight. 5 dwg
