  • TURBINE ENGINE VANE ARRANGEMENT HAVING A PLURALITY OF INTERCONNECTED VANE ARRANGEMENT SEGMENTS
    Publication number: 20200024998
    Abstract: A turbine engine vane arrangement and a method for manufacturing a turbine engine vane arrangement are provided. The vane arrangement includes a plurality of vane arrangement segments arranged circumferentially around an axial centerline. Each of the vane arrangement segments includes an airfoil that extends radially between a first platform segment and a second platform segment. The first platform segment extends circumferentially between a first mate face and a second mate face. The first mate face of a first of the vane arrangement segments is bonded to the second mate face of a second of the vane arrangement segments.
