OPTIMIZED AERODYNAMIC PROFILE FOR A TURBINE BLADE
First Claim
1. An aerodynamic profile of a turbine blade, wherein, when cold and in the uncoated state, said 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′
is the quotient D/H where D is the distance from the point in question to a reference plane P0, situated at the base of the nominal profile and H is the height of this 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, while the coordinate X is measured in the axial direction of the turbine and the height H being 43 mm±

Abstract
When cold and in the uncoated 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′ is the quotient D/H where D is the distance from the point in question to a reference plane P0 situated at the base of the nominal profile and H is the height of this profile, measured from the reference plane to the tip of the blade. The measurements D and H are taken radially relative to the axis of the turbine, while the coordinate X is measured in the axial direction of the turbine.
