VANE ARC SEGMENT WITH THERMAL INSULATION ELEMENT

VANE ARC SEGMENT WITH THERMAL INSULATION ELEMENT

A vane arc segment (60) includes an airfoil piece (62) that defines first and second platforms (64, 66) and an airfoil section (68) that extends between the first and second platforms (64, 66). The first platform (64) defines a gaspath side (64a), a non-gaspath side (64b), and a first platform radia...

Zusammenfassung:A vane arc segment (60) includes an airfoil piece (62) that defines first and second platforms (64, 66) and an airfoil section (68) that extends between the first and second platforms (64, 66). The first platform (64) defines a gaspath side (64a), a non-gaspath side (64b), and a first platform radial flange (72) that projects from the non-gaspath (64b) side. Support hardware (74) supports the airfoil piece (62) via the first platform radial flange (72). A thermal insulation element (76) is situated adjacent the first platform radial flange (72). The support hardware (74) supports the airfoil piece (62) through the thermal insulation element (76).
