Military jet aircrafts require minimum thrust while cruise and maximum thrust during take-off or manoeuvres and/or emergencies. The best way for supplying the additional thrust is the afterburner with least weight penalty. The disadvantages with afterburner are the high-frequency instabilities which are detrimental to the aircraft. Hence, CFD followed by acoustic analysis is attempted, for different equivalence ratios in the afterburner, to suggest the best equivalence ratio for the absorption of acoustic energy. Maximum transmission loss, representing maximum absorption of acoustic energy, was observed for the equivalence ratio of 0.58.
