FIELD: transport.SUBSTANCE: invention relates to devices for lifting and transfer in air. Proposed method consists in application of the main disc with flexure at its edge and serial identical-orientation helical ribs located abode the main disc surface to create lower pressure at drive rotation. Main disc central part has flexed bore to ensure drive stiffness and clamping while extra disc is arranged there above and locked at the drive rotary part. For joint rotation, said ribs are locked and have slits made at their bottom part to receive one or several serial sliding plates to reciprocate perpendicular to and over main disc surface, on the entire length of said helical rib.EFFECT: increased lift.2 cl, 2 dwg |
