Abstract
When cold and in the non-coated state, the aerodynamic profile is substantially identical to a nominal profile determined by the rectangular coordinates X,Y,Z' given in Table 1, in which the X coordinate is measured in the axial direction of the turbine, and the Z′ coordinate is the quotient D/H, where D is the distance of the point in question from a reference plane Psituated at the base of the nominal profile and H is the height of the profile measured from said reference plane to the tip of the blade, the measurements D and H being taken radially relative to the axis of the turbine.
