<p>A rotary machine vane (30) includes a body (62) and an articulated tip (64) pivotally joined thereto. The body (62) is complementary with a slot (28) of a rotor (14) in which it is mountable for radial reciprocation therein. The body (62) includes an arcuate cradle (66) extending axially along a radially outer end thereof. The vane tip (64) includes a pin (64a) and an integral plate (64b) extending along the pin (64a) for facing a casing (20) surrounding the rotor (14) to form a seal (68) therewith. The pin (64a) is complementary to the cradle (66) for defining a radial gap (70) therebetween, and is radially outwardly retained by the cradle (66) for rocking movement therein for self-alignment with the casing (20).</p> |
