Stator vane of a variable-geometry turbine

A vane (32) for a stator (11) of a variable-geometry turbine (1), in particular for aeronautical engines, has an airfoil profile (33) and a pair of hinge portions (36, 37), which are carried by the airfoil profile (33) and enable the airfoil profile (33) to be coupled to a support structure (20, 21)...

Beschreibung
Zusammenfassung:	A vane (32) for a stator (11) of a variable-geometry turbine (1), in particular for aeronautical engines, has an airfoil profile (33) and a pair of hinge portions (36, 37), which are carried by the airfoil profile (33) and enable the airfoil profile (33) to be coupled to a support structure (20, 21) of the stator (11) so as to be rotatable about an axis of adjustment (40); the vane (32) also has internal channels (81, 86) that allow a flow of air to pass through in order to cool the hinge portions (36, 37).
