FIELD: machine building.

SUBSTANCE: blade screw for use with fluids intended for movement of object or person or for movement of fluid medium, comprises a plurality of blades, means for creating non-axial lifting force and non-axial flow of fluid medium, means for changing direction of non-axial flow of fluid medium to axial flow of fluid medium and axis of rotation, coinciding with hub. Plurality of blades protrudes radially outward from rotational axis and is located around axis of rotation. Each blade forms a loop-like structure and has an inlet section, an outlet section and an end section extending radially outward from the axis of rotation. Generator of non-axial lifting force and non-axial flow of fluid medium is blade. Device has a blade propeller and is selected from a group consisting of propulsors, closed blade propellers, sealed blade propellers, impellers, aircraft, swimming devices, turbines, including wind turbines, cooling devices, heating devices, automobile engines, drones, turbo-ventilators, hydroelectric units, air circulation devices, compressors and jet pumps.

EFFECT: group of inventions is aimed at expansion of technical facilities array.
