Method and apparatus for gas turbine engines

摘要

A heat shield assembly (100) for a gas turbine engine combustor is provided. The combustor (16) includes a domeplate (70) and at least one fuel injector (58) extending through an opening (80) in the domeplate. The heat shield assembly includes a heat shield (110) coupled against a downstream side of the domeplate, a threaded collar (124) extending upstream from the heatshield, the threaded collar received within the domeplate opening, and a retainer (112) coupled to the collar such that the domeplate is securely coupled between the heat shield and the retainer.
