Abstract (en)
[origin: WO2016005834A1] A turbine is described for the expansion of a compressible operating fluid, for example gas or steam. The turbine comprises a first group of stages, named stages of first expansion, that extends in a radial centripetal direction in order to carry out a first centripetal expansion and a second group of stages, named stages of second expansion, that extends downstream of the stages of first expansion in order to carry out a second centrifugal expansion. The arrays of rotor blades of the stages of first expansion are constrained to a first shaft and the arrays of rotor blades of the stages of second expansion are constrained to a second shaft coaxial with respect to the first shaft, and are interposed between additional arrays of rotor blades constrained to the first shaft. The first shaft rotates at a speed higher than the second shaft, and in an opposite way. The rotors carrying the arrays of rotor blades are constrained in a 'cantilevered' configuration to the respective shafts at an end thereof.
