Abstract
The invention refers to a flameholder device for afterburners in gas turbine engines with a cooling air fan of by-pass type, comprising a plurality of radial flameholder means ( ) which at their radially outer end are mounted to the afterburner casing ( ) and have a longitudinal air channel which ends at the radially inner end of said means ( ), at which end is arranged a circumferentially extending arcuate flameholder gutter. In order to provide for a relief of the stresses from said flameholder device on the casing ( ) it is suggested according to the invention that the flameholder means ( ) at their radially outer ends each are pivotably and releasably mounted to said casing and in that the gutters of the respective flameholder means are formed as a common integral annular supporting and load-carrying body ( ).
