An afterburner for a turbofan engine is disclosed having a plurality of connecting arms connecting the inner wall to the outer wall wherein each of the connecting arms defines an air chamber, an inlet communicating with the main air bypass passageway and a plurality of outlets communicating with the afterburner chamber. The plurality of connecting arms are distributed generally radially about the longitudinal axis of the engine and serve to distribute a portion of the bypass air into the afterburner chamber. The bypass air is further distributed into the afterburner chamber through a plurality of flame holders extending radially inwardly from the outer wall towards the longitudinal axis. Each of the flame holders also defines an air chamber, an inlet communicating with the main air bypass passageway and a plurality of air outlets. The flame holders may also be distributed in a radial array about the longitudinal axis and are interposed between adjacent connecting arms.
