When cold and in the non-coated state, an aerodynamic profile defining an arm of a structural casing of a turbine having a central hub and a shroud is 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 plane Psituated at a base of the nominal profile, and H is a height of said nominal profile measured from the first reference plane to a second reference plane P. The measurements D and H are taken radially relative to an axial direction of the turbine, while the X coordinate is measured in the axial direction of the turbine.

Optimized aerodynamic profile for an arm of a structural casing of a turbine, and structural casing having such an arm

When cold and in the non-coated state, a turbine blade includes an aerodynamic profile that 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 Psituated 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 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.

Optimized aerodynamic profile for a turbine blade, in particular for a rotary wheel of the third stage of a turbine

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.

Optimized aerodynamic profile for a turbine vane, in particular for a nozzle of the sixth stage of a turbine

When in a cold state and in a non-coated state, the aerodynamic profile for an arm of a structural casing of a turbine having a hub and a shroud is substantially identical to a nominal profile determined by specific Cartesian coordinates X,Y, Zadim. The coordinate Zadim is the quotient D/H where D is a 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 said 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.
