1. A rotor for the first phase having a series of blades each defined by coordinates of a discreet combination of points,
in a Cartesian reference system (X,Y,Z), wherein the axis (Z) is a radial axis intersecting the central axis of the turbine,
the profile of each blade being identified by means of a series of closed intersection curves between the profile itself and
planes (X,Y) lying at distances (Z) from the central axis, each blade having an average throat angle defined by the cosine
arc of the ratio between the average throat length at mid-height of the blade and the circumferential pitch evaluated at the
radius of the average throat point, wherein the average throat angle ranges from 54.9° to 57.9°, and further wherein said
closed curves are defined according to Table I, whose values refer to a room temperature profile and are divided by the value,
expressed in millimeters, of the axial chord referring to the most external distance (Z) of the blade.
