摘要： A turbine (1), at least partially centrifugal, for the expansion of a compressible operating fluid, for example gas or steam. At least one group of stages (5), named centrifugal stages, extends in a radial direction with respect to the axis X-X to carry out the centrifugal expansion of the operating fluid.

Moreover, all the arrays of rotor blades are constrained to the shaft (2) at an end thereof, anyway not in the area between the bearings (9), i.e. according to a so-called "cantilevered" configuration and particularly advantageous to carry out maintenance operations. The proposed solution allows high efficiencies to be achieved by a compact turbine. A corresponding method for expanding the operating fluid is further described.
