Turbine rotor for air cycle machine

A turbine rotor for an Air Cycle Machine comprising:

• a hub with a multiple turbine blades which extend therefrom, each of said multiple of turbine blades have a tip contour defined by a set of points in Table C-1 scaled by a desired factor, said set of points include paired axial dimension K from a centerline of the turbine rotor and a radial dimension J from a reference surface.
