FIELD: machine building.
SUBSTANCE: invention relates to aircraft engine building, to propeller-driven aircraft gas turbine engines with rear arrangement of two-row open (non-turned over) propeller fan, to gas turbine engines of super-high degree of double circuit. Technical result is achieved due to that propeller fan gas turbine engine comprising fan 5, gas generator 6 and low pressure turbine 7, behind which power housing 8, in which reduction gear 9 is installed, mechanically connected to propeller fan 2 with counterrotating blades 3, and gas and air mixer 10 located at inlet of gas-air channel of propeller fan, jet nozzle 4. Engine is made double-circuit, at that annular channel 11 of the second circuit from fan 5 through mixer 10 of gas and air is interconnected with gas-air channel of propeller fan 2, and reduction gear 9 is mechanically connected to turbine 7 of low pressure.
EFFECT: technical result, achievement of which is the proposed invention is improvement of reliability and service life of propeller fan gas turbine engine.
