Airfoil anti-rotation ring and assembly

A method of assembly, the method comprising:

• locating a plurality of vanes about an inner circumference of a ring;
• and
• aligning a notch on a radially outer platform of each of the plurality of vanes with a corresponding axially extending projection on the ring to prevent the plurality of vanes from rotating relative to the ring.

An assembly for a gas turbine engine comprising:

• a vane disposed about an axis and having a radially outer platform, a flange projecting radially outwardly from the radially outer platform, and a notch extending axially through the flange such that the notch opens at forward and aft flange faces of the flange;
• and
• a ring located radially outward of the radially outer platform, the ring having axially forward and aft ring faces and a lug extending axially from the forward ring face, the lug extending axially through the notch on the flange and limiting circumferential movement of the vane.
