摘要： A high-performance turbine (1a, 1b), particularly with increased specific power, comprising a rotor (2) and a distribution apparatus (3a, 3b) which is adapted to convey a fluid stream (4) onto the elements of the rotor (2) for the rotation of the rotor (2) about its own rotation axis (5). More precisely, the rotor (2) comprises a plurality of thrust ducts (6) adapted to receive the fluid stream (4) conveyed by the distribution apparatus (3a, 3b) to generate a rotary thrust on the surrounding walls of the thrust ducts (6). The particularity of the invention resides in that it comprises at least one slot (23, 24, 25, 26), which is formed on the walls of the thrust ducts (6) and/or of the distribution apparatus (3a, 3b) and is adapted to connect the fluid stream (4) to the outside environment of the turbine (1a, 1b). At least one of the thrust ducts (6) and the distribution apparatus (3a, 3b) crossed by the fluid stream (4) comprises at least one portion that converges in the direction in which the fluid stream (4) travels, which is defined upstream of the slot (23, 24, 25, 26) in the direction of travel of the fluid stream (4) for the at least local lowering of the pressure inside the thrust ducts (6) and/or the distribution apparatus (3a, 3b), which are crossed by the fluid stream (4), below the value of the pressure of the filling fluid (22) of the outside environment, with consequent suction of the filling fluid (22) into the thrust ducts (6) and/or the distribution apparatus (3a, 3b) which are crossed by the fluid stream (4).
