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, Zadim given in Table 1, in which the coordinate Zadim is the quotient D/H where D is the distance of the point under consideration from a first reference plane P0 situated at the base of the nominal profile, and H is the height of said profile measured from the first reference plane to a second reference plane P1. 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.
An aerodynamic profile for a turbine blade, the profile being, when cold and in a non-coated state, substantially identical to a nominal profile determined by Cartesian coordinates X,Y,Zadim given in Table 1, in which the coordinate Zadim is a quotient D/H, where D is a distance of a point under consideration from a first reference X,Y plane situated at a base of the nominal profile, and H is a height of said profile measured from said first reference plane that is the intersection of a stacking axis of a set of blades and an axisymmetric surface of a hub, out to a second reference plane that is an intersection of said stacking axis with an axisymmetric surface of a casing, the measurements D and H being taken radially relative to an axis of a turbine, while the coordinate X is measured in the axial direction of the turbine.
