Turbine engine vane arrangement having a plurality of interconnected vane arrangement segments

A method for manufacturing a turbine engine vane arrangement comprising a plurality of vane arrangement segments that include a plurality of base segments and a keystone segment, each of the vane arrangement segments comprising an airfoil extending radially between a first platform segment and a second platform segment, the first platform segment extending circumferentially between a first mate face and a second mate face, the method comprising:

• physically arranging the base segments circumferentially around the axial centerline;
• measuring a width of a keystone gap extending between a pair of the base segments, wherein the width of the keystone gap is different than a width of each of the base segments;
• machining at least one of the pair of the base segments based on the measured width such that the keystone segment circumferentially fits within the keystone gap;
• physically arranging the keystone segment between the pair of the base segments;
• and
• connecting the vane arrangement segments together, wherein the connecting comprises bonding the first mate face of a first of the vane arrangement segments to the second mate face of a second of the vane arrangement segments.

A method for manufacturing a turbine engine vane arrangement, comprising

• providing a plurality of vane arrangement segments that consists of a plurality of base segments and a keystone segment, each of the vane arrangement segments comprising an airfoil extending radially between a first platform segment and a second platform segment, the first platform segment extending circumferentially between a first mate face and a second mate face, and the first platform segment of each of the vane arrangement segments comprising a width that is equal to a first value and extends circumferentially between the first mate face and the second mate face;
• physically arranging the base segments circumferentially around an axial centerline;
• measuring a width of a keystone gap extending between a pair of the base segments;
• machining the keystone segment based on the measured width, the machining comprising machining at least one of the first mate face and the second mate face of the keystone segment such that the width of the keystone segment has a second value that is less than the first value;
• physically arranging the keystone segment between the pair of the base segments;
• and
• connecting the vane arrangement segments together, wherein the connecting comprises bonding the first mate face of a first of the base segments to the second mate face of the keystone segment.
