FIELD: turbine construction.
SUBSTANCE: invention relates to turbine (1), partially centrifugal, for expanding a compressible working fluid, such as gas or steam. Above turbine preferably comprises a group of steps called centripetal steps (4), extending radially relative to the axis X-X, which enables the first expansion of the working fluid radially and centripetally. In addition, all gratings of the rotor blades are attached to the end of shaft (2), but not in the area between the bearings, that is, in accordance with the so-called “cantilever” design, and particularly preferably with the provision of maintenance. Also, an appropriate method for expanding the working fluid is described.
EFFECT: technical result: provides the possibility of achieving high efficiency through a compact turbine.
