VANE WITH SEAL AND RETAINER PLATE

A vane (60) includes a vane piece (62) that defines a first vane platform (66), a second vane platform (68), and a hollow airfoil section (70) that joins the first vane platform (66) and the second vane platform (68). The first vane platform (66) defines a collar (74) that projects therefrom. A spar piece (64) defines a spar platform (76) and a spar that extends from the spar platform (76) into the hollow airfoil section (70). A retainer plate (84) is bonded to the spar platform (76). The retainer plate (84) and the spar platform (76) define a groove (86), and there is a seal (88) trapped in the groove (86). The seal (88) seals against the collar (74) of the first vane platform (66).
