Abstract:
A vane (32) for a stator (11) of a variable-geometry turbine (1) for aeronautical engines; the vane comprising an airfoil profile (33) and means for coupling (36, 37) said airfoil profile (33) to a support structure (20, 21) of said stator (11); characterised in that said coupling means (36, 37) comprise hinge means (36, 37) carried by said airfoil profile (33) to allow the airfoil profile (33) to rotate with respect to said support structure (20, 21) about an axis of adjustment (40), and in that said coupling means comprises means for both cooling (81, 86) said hinge means (36, 37) and sealing said vane (32) to said support structure (20. 21).
