FIELD: flying vehicles, ground-effect craft, seaplanes, sea-going and river vessels. SUBSTANCE: propeller has at least one horizontal or inclined screw which is fully or partially immersed in flow of liquid or gas and is rotated by engine; propeller is provided with retreating and advancing blades, guide compensator connected with case of flying vehicle or hull of water craft; it is interacting with induced flow of advancing blades. Guide compensator may be made in form of straightening device located under advancing blades and provided with straightening and/or deflecting vanes when it is necessary to increase lifting force or lifting and motive forces; it may be made in form of radial or radial-axial branch (branches) fitted with outlet nozzle (nozzles) when it is necessary to increase motive force and reduce resistance; it may be made in form of branch to lifting complex of ground-effect craft when it is necessary to create pressure in air cushion. EFFECT: enhanced reliability. 4 cl, 12 dwg
