摘要： A low turbulance, close-coupled mounting structure for a flame holder disposed in an afterburner section of a gas turbine engine is provided. The afterburner section has a plurality of angularly spaced, radially extending fuel injection nozzles (16), with a fairing (20) surrounding each nozzle to form open ended heat shields about the nozzles. A flame holder (22) having a first cross-sectional configuration is disposed in recessed portions (40) formed in the fairings surrounding the nozzles. The cross-sectional configuration of the recessed portions is configured to substantially conform to a portion of the cross-section of the flame holder such that the flame holder is recessed into the fairings when mounted thereon, thus eliminating outward projections at the connection of the flame holder and fairings. The flame holders are secured in the recessed portions by pins (84) extending through aligned apertures (82) in the skirts (72, 74) of the flame holder.
