The turbine contains a diffuser () in the form of a rotational body, the wall of which has the shape of a convex-concave aeronautical profile in the axial section and a rotor () with blades () rotating in the plane of a throat (R) of the diffuser () and connected with a hub () by lower ends. The lower ends of the blades () are set away from the surface of the hub () by the dimension of the lower gap (z), the dimension being determined by the height of connectors () mounted to the lower ends of the blades () and to the hub (), the dimensions of the upper gap (z) between the upper ends of the blades () and the surface of the throat (R) and the lower gap (z) have dimensions ranging from 0.5 to 15% of the radius of the throat (R), preferably from 3 to 8%. The upper gap (z) is determined by the height of the connectors () mounted to the upper ends of the blades () and to the rotational ring () which rotates in the circumferential recess () of the diffuser () and the inner surface of which has a shape of the throat (R). Furthermore, the ratios of the dimensions of the upper gaps (z) and the lower gaps (z) to the corresponding lengths of chords (c, c) on the ends of blade () of the profiles have values ranging from 0.20 to 2.5, preferably from 0.6 to 1.2. 1.
