FIELD: machine building.
SUBSTANCE: invention relates to air and water propulsors, which provide translational movement of corresponding vehicles. Propulsor consists of a body, two or more vane contours arranged inside the body and revolving towards each other. Contours are coaxially set one inside the other, at that the blades are located parallel to the rotation axis. On the propulsor body there are from 4 to 7 air intakes having an annular shape, made in the form of alternating staggered projections. Ledge of the next air intake is combined with the recess of the previous one. Length of propulsor is three times larger than its diameter.
EFFECT: reduced area of cross section of propulsor with retention of its traction characteristics.
