摘要： The invention refers to a flameholder device, particularly for ram-jet engines and after-burners in turbojet engines and comprising an annular body (2) coaxial with the centre axis of the engine and formed by a plurality of circumferentially spaced thin-walled metal guide vanes (4), upstream of which fuel nozzles (1) are mounted and downstream of which a turbulent combustion-stabilizing zone is formed, said guide vanes (4) being hollow and having relatively great volume and which, if desired, are cooled by means of air flowing therethrough, the guide vanes furthermore being protected by a ceramic material (3). In order to prevent the intrusion of the fuel-air mixture into the internal space of said guide vanes should cracks occur in said vanes and hence accompanying destructive burning thereof, it is suggested according to the invention that the ceramic material is made as a closed box-like insert body (3) arranged within the cavity in the guide vanes and with its external surface all around lying close to the internal surface of the guide vane walls and which either is hollow in itself and in the case of cooling by means of a flow of air therethrough have openings corresponding to the through-flow openings in the guide vane walls or is filled with a porous ceramic material or entirely consists of such porous material.

摘要： 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 (1) which at their radially outer end are mounted to the afterburner casing (2) and have a longitudinal air channel which ends at the radially inner end of said means (1), 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 (2) it is suggested according to the invention that the flameholder means (1) 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 (14).
