A reliable reduced weight coaxial lifting system includes a reducing gear with two shafts rotating in opposite directions, upper and lower rotor hubs mounted on the respective shafts and upper and lower swashplates connected to one another, which are movable in the axial direction and are kinematically linked to guides of blades positioned on the upper and lower rotor hubs. Guides of the blades are connected to the upper swashplate by rockers mounted on a slide block located above the upper rotor hub and guides of the blades of the lower rotor hub are connected by tie rods directly to the lower swashplate. The lower swashplate is connected to control systems of a collective and a cyclical pitch and the slide block is connected to a control system of a differential pitch of the upper rotor.
