Patent ID: 7596949

Claim:
A method for fabricating a gas turbine engine combustor that includes a domeplate and at least one fuel injector extending through an opening in the domeplate, said method comprising: fabricating a heatshield that includes a threaded collar extending upstream from the heatshield and a plurality of slots configured to receive a respective anti-rotation tab; positioning the heatshield on a downstream side of the domeplate such that the threaded collar is received within the domeplate opening; coupling a retainer to the collar on an upstream side of the domeplate such that the domeplate is securely coupled between the heat shield and the retainer fabricating a spacer that includes a plurality of anti-rotation tabs; and coupling the spacer between the retainer and the domeplate upstream side to the threaded coupling such that the anti-rotation tabs extend through the heatshield slots and at least partially into the heatshield to facilitate securely coupling the heat shield to the domeplate.
