This invention discloses a vibration damper for an afterburner with an insertion tube, belonging to the design field of afterburners. It includes a vibration damper, a flame stabilizer, and a central cone. The vibration damper is located at the downstream end of the outer bypass channel, closely attached to the inner wall of the afterburner shell, forming a double-wall structure. Cold air from the outer bypass flows through it, cooling the wall surface and absorbing oscillation energy, thus suppressing high-frequency vibrations in the combustion chamber.

The inner bypass and part of the outer bypass airflow meet here, forming a low-speed recirculation zone, achieving fuel-air mixing and stable ignition. The vibration damper has openings, employing a deep-hole structure with an insertion tube. The insertion tube is placed within a hole in the vibration damper's base, significantly increasing the equivalent neck length of the vibration damper while maintaining the same main plate thickness. This shifts the peak sound absorption frequency towards lower frequencies, improving the vibration damper's absorption capacity for low-frequency oscillation modes in the afterburner.
