Abstract:
A flameholder is disclosed for use in an afterburner of an aircraft gas turbine engine. The flameholder comprises at least one annular ring and a plurality of open ended slots around the forward end of the ring with the open end of each slot open through the forward edge of the ring for accepting a plurality of fuel spraybars. One particular embodiment provides two or more sub-pluralities of slots having two or more differing axial lengths to accommodate different axially spaced sub-pluralities of spraybars such as primary and pilot spraybars. A fastening means is provided for attaching the annular ring to the outer engine casing and is accessible through the exhaust nozzle of the engine. One embodiment provides a fastening means with an anti-rotation means on a connecting link into which a bolt head may be slipped and held from rotating during torquing of a nut. Another feature of the present invention is the use of a bolt having a thread diameter smaller than the bolt shank diameter which is particularly useful when the threads are seized due to high temperature exposure.
