FIELD: engines and pumps.
SUBSTANCE: proposed system incorporates free power turbine including first rotor, first and second propellers running in opposite directions about system lengthwise axle relative to system stator, and mechanical gearing. Said mechanical gearing comprises epicycloidal transfer mechanism including planetary gear centered on said lengthwise axle and drive by said first rotor of free power turbine. Besides, it comprises at least one planet gear engaged with said plant gear. Also it has pinion carriage to drive said first propeller. Besides it incorporates crown gear engaged with every planet gear to drive said second propeller. Free power turbine comprises also the second rotor running in opposite direction relative to said first rotor to drive said crown gear.
EFFECT: decreased total weight of propeller system, lower load at engine suspension.
