FIELD: engines and pumps.
SUBSTANCE: turbo-fan engine comprises two gas generators consisting of axial compressor, combustion chamber and turbine arranged along shared airflow, and nozzles. Additionally, it incorporates nacelle shared by aforesaid gas generators, common two-stage free turbine mounted between gas generators and running in opposite directions to transmit torques with the help of two one-stage reductions gears and two shafts mounted in parallel between gas generators and to auger-type fan mounted in nacelle.
EFFECT: higher reliability and operating economy.
