ABSTRACT:
A flameholder for a gas turbine engine includes a retainer plate on the igniter holder boss which protrudes from the flameholder gutter and extends through a clearance hole in the outer shroud. The retainer plate permits thermally induced growth of the parts but does not allow the fuel spray and air flow gap near the igniter to increase significantly, thus assuredly maintaining a sufficiently rich fuel/air mixture to promote ignition.
