FIELD: engines and pumps.SUBSTANCE: claimed engine comprises compressor and two-stage turbine, low-pressure compressor with compressor mounted at outlet of the latter. Two-stage turbine second stage nozzle blade inner cavity inlet is connected with compressor mid stage via the cooling air flow rate control shutter. Besides, said turbine is equipped with turbine outer housing blowing system. The latter inlet is connected to airflow changeover mechanism, its inlet being connected with compressor outlet and low-pressure compressor outlet.EFFECT: higher reliability and efficiency due to smaller gaps between turbine rotor and stator.2 dwg |
