Original Abstract Submitted
A gas turbine engine includes first and second CMC vane arc segments arranged about an engine central axis. Each of the CMC vane arc segments has a platform and an airfoil section that extends off of the platform. The platform defines an axially trailing face, an axially leading face that is circumferentially offset from the axially trailing face, and first and second circumferential faces that extend from the axially trailing face to the axially leading face. The first circumferential face of the first CMC vane arc segment interfaces with the second circumferential face of the second CMC vane arc segment. There is at least one friction damper between the first circumferential face of the first CMC vane arc segment and the second circumferential face of the second CMC vane arc segment.
