<p>A high-performance turbine, particularly with increased specific power, including a rotor and a distribution apparatus which is adapted to convey a fluid stream onto the elements of the rotor for the rotation of the rotor about its own rotation axis, where the rotor includes a plurality of thrust ducts adapted to receive the fluid stream conveyed by the distribution apparatus to generate a rotary thrust on the surrounding walls of the thrust ducts, the turbine further including at least one slot, which is formed on the walls of the thrust ducts and/or of the distribution apparatus and is adapted to connect the fluid stream to the outside environment of the turbine, where at least one of the thrust ducts and the distribution apparatus crossed by the fluid stream includes at least one portion that converges in the direction in which the fluid stream travels, which is defined upstream of the slot in the direction of travel of the fluid stream for the at least local lowering of the pressure inside the thrust ducts and/or the distribution apparatus, which are crossed by the fluid stream, below the value of the pressure of the filling fluid of the outside environment, with consequent suction of the filling fluid into the thrust ducts and/or the distribution apparatus which are crossed by the fluid stream.</p> |
