초록

A cooled turbine guide vane comprises a hollow aerodynamic portion between inner and outer platforms. The interior of the aerodynamic portion is partitioned into a leading edge duct and a main cavity in which a perforated tubular member is disposed, being spaced from the intrados and extrados side walls of the vane by longitudinal ribs. The tubular member is divided by a partition into two cavities on the intrados and extrados sides of the partition. A first cooling circuit is constituted by the leading edge duct and the intrados cavity of the tubular me...
