ABSTRACT:
A radial flameholder (18) extends from the augmentor case (22) through an opening (30) in a coaxial liner (20) and into the hot exhaust gas stream (26). A portion of a cool, annular fan air stream (28) enters an upstream facing opening (34) and discharged radially inwardly adjacent the downstream edge (44) of the liner opening (30). The inner flow (42) of cool air protects the liner (20) downstream of the flameholder (18) by both cooling the liner (20) locally and by displacing the combustion reaction (32) attached to the flameholder (18).
