Abstract
A flameholder structure for a turbojet engine afterburner is disclosed in which a generally 'V' shaped flameholder ring has a plurality of substantially radially extending fins attached to and extending radially outwardly from its outer surface. A portion of each of the fins is disposed at an angle to the gas flow so as to impart a cylindrical rotation to that portion of the flow passing over the fins. The cylindrical rotation of the flow increases the shear effect to thereby improve the stability of the flame front and increase the efficiency of the afterburner.
