Abstract
A gas turbine engine includes a turbine section that has inner and outer diameter full hoop ceramic support rings that define an annulus there between and ceramic vane arc segments disposed in the annulus. Each segment has radially outer and inner platforms and an airfoil section. The radially outer platform includes an outer platform flange. The radially outer full hoop ceramic support ring axially constrains each of the ceramic vane arc segments via the outer platform flanges, and the radially outer diameter full hoop ceramic support ring radially constrains each of the ceramic vane arc segments at a location adjacent an axially-facing trailing side of the radially outer platform. The radially inner diameter full hoop ceramic support ring radially constrains each of the ceramic vane arc segments at a location adjacent the axially-facing leading side of the radially inner platform.
