FIELD: transport.
SUBSTANCE: invention relates to fan-duty equipment, in particular, to aircraft and air-cushion apparatus propulsors. Proposed propulsor comprises housing made up of perforated cylinder with guide branch pipe and active nozzle, active air feed device made up of reverse driver and flow accelerator. Flow accelerator tunnel tune inner surface is provided with vanes arranged in opposition to reversible central vanes screw mounted on central hollow shaft. Said runs in housing grid bearings to support output central vaned screw at cantilever section. Besides, air propulsor comprise guide branch pipe furnished with grid with active nozzle secured thereon. Note here that nozzle cone covers but partially the flow accelerator active zone while extension barrel is provided with horizontal thrust branch pipe that may turn axially.
EFFECT: decreased overall dimensions.
