When cold and in the non-coated state, the aerodynamic profile is substantially identical to a nominal profile determined by the Cartesian coordinates X,Y,Z' given in Table 1, in which the coordinate Z&#x2032; is the quotient D/H where D is the distance of the point under consideration from a first reference plane Psituated at the base of the nominal profile, and H is the height of the profile measured from the first reference plane to a second reference plane P. The measurements D and H are taken radially relative to the axis of the turbine, while the X coordinate is measured in the axial direction of the turbine.
