Patent ID: 7419353

Claim:
A fixed turbomachine blade with a profile skeleton line extending along a meridional flow line, the blade being radially divided into at least a mid zone and two peripheral zones with profile skeleton lines for a zone of the blade at a firmly attached end remaining below a limiting line given by the following equation: α*=−3.3550017483 S* 6 +12.8091744282 S* 5 −19.1276527122 S* 4 +14.1735887616 S* 3 −5.4814126258 S* 2 +1.9327011304 S* +0.0513455055 where; α * = α 1 - α P α 1 - α 2 S * = s P S and P is any point of the profile skeleton line, α 1 is an angle of inclination at a blade leading edge, α 2 is an angle of inclination at a blade trailing edge, α* is a dimensionless, specific angle of a total curvature, S* is a dimensionless, specific extension, α p is an angle of a tangent at any point P of the profile skeleton line to a central meridional flow line, s p is an extension of the profile skeleton line at any point P, and S is a total extension of the profile skeleton line.
