FIELD: transport.
SUBSTANCE: system 1 of aircraft gas turbine opposite-rotation propellers comprises first and second propellers 6, 8, respectively, each including blade control system 25, 26. Said system comprises rotary means 38, 68 to allow slider 28, 58 displace to turn blades to preset angles of attack. In compliance with this invention, said system comprises additionally clutches 72 to couple revolving first and second drive revolving means 38, 68. Note here that said system is configured to create relative rotational speed, on throwing in said clutches, between sliders 28, 58 and appropriate drive revolving means 38, 68 to make blades 6a, 8a feathering.
EFFECT: fast and reliable feathering of blades of both propellers.
