An air-blowing propeller has a blower with two rotary wheels mounted on its shaft and directed in opposite directions. Air supply to the blower is carried out through the front channel with a divider. The rotary wheels of a blower consist of spiral walls fixed between flange discs and discs with input windows, curved with a flow radius in polar coordinates. The outlet from the blow nozzles of blower is passed through transition tubes to the driving nozzles, which are built into the rear edges of the wings with possibility of forwarding the air back with deviations for a desired angle up or down and are made in the form of straight pipes consisting of a short cylindrical part for sliding sealing of nozzles with a taper, and outside for fastening a rope, by which the nozzle is turned for an angle around their axis, and a long conical part with a slot along it and a centring-thrust bearing. |
