FIELD: aero-engine manufacture. SUBSTANCE: jet engine is provided with air turbine, second loop and straightening grid before compressor. Power and air turbine are provided with special mechanism for shifting them from one mode to another. Circular passage for feeding the compressed air to additional combustion chamber is provided with air preheaters, circular slot for connection with main combustion chamber and shut-off ring driven by pneumatic cylinders mounted in streamlined wells with covers. Additional combustion chamber is mounted in after-turbine space where combustion chamber is used as well and terminates in cooled fairing with exhaust branch pipe. Mixer is mounted after additional combustion chamber. EFFECT: increased thrust of engine. |
