Wavy-edged flange for gas turbine engine double row stator assembly

A method of making a double row stator assembly for a gas turbine engine comprising:

• integrally forming, using a continuous additive manufacturing (AM) technique, a first vane row stator assembly, a plurality of first-row vanes, a second vane row stator assembly, a plurality of second-row vanes, and a wavy-edged flange;
• wherein
• the first vane row stator assembly includes the plurality of first-row vanes;
• the second vane row stator assembly includes the plurality of second-row vanes,
• wherein the second vane row stator assembly is configured to be positioned to be sequentially downstream of the first vane row stator assembly when the first vane row stator assembly and the second vane row stator assembly are assembled to form the double row stator assembly such that trailing edges of the first-row vanes overlap leading edges of the second-row vanes;
• and
• the wavy-edged flange is configured to secure the first vane row stator assembly to the second vane row stator assembly when the first vane row stator assembly and second vane row stator assembly are assembled to form the double row stator assembly.
