Afterburner Flameholder Construction.
Patent, Filed 25 Jun 87, patented 28 Mar 89,
DEPARTMENT OF THE AIR FORCE WASHINGTON DC
Pagination or Media Count:
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 fuelair mixture to promote ignition. jes
