The invention relates to a system (25), comprising: a linear actuator (26) axially arranged in the first propeller (9) and rotatably secured thereto, a first linking mechanism (27) connecting the rod of said linear actuator (26) to the second propeller (9) in order to change the setting of the blades thereof, and including an intermediate bearing (35) between the propellers, which is capable of transmitting the translation of the rod of the actuator (26) and disconnecting the rotatable link to the first propeller (8) in order to make it possible to change the setting of the blades of the second propeller (9) rotated in the opposite direction to the former, and a second linking mechanism (28) combined with the blades of the first propeller (8) in order to change the setting thereof.
