More Information
Summary:An afterburner assembly is disclosed in which the flameholder ring is formed by plurality of flameholder ring segments, each segment being integrally formed with a generally radially extending arm. The flameholder ring segments extend beyond each opposite sides of the arm. The arm and flameholder ring segments are attached to the casing of the afterburner by a support element which is pivotally attached to the arm and fixedly attached to the afterburner casing. The distal end of the arm slidably contacts the casing defining the opposite side of the afterburner duct to enable the arm to slide relative to the casing to allow for differential thermal expansion of the respective elements. When each of the arm/flameholder ring segments are attached to the afterburner casing, the flameholder ring segments form a generally annular flameholder ring. The ring has a generally "U"-shaped cross-sectional configuration with the legs of the "U"-shape extending generally parallel to a central axis and opening in a downstream direction according to the gas flow flowing through the afterburner duct.
