    Abstract

    This paper deals with a novel technique of ignition for afterburners of aircraft engines system, consists of the injection of hydrazine on to a lusted iron catalyst surface suitably located in the afterburner, resulting in an intense hot spot caused by spontaneous decomposition of hydrazine. This hot spot serves as the source of ignition for the fuel - air mixture. This technique has been demonstrated by experiments on the model afterburner13; using kerosene as e.fuel. This novel technique, called erogenic Ignition The paper describes the experimental set-up and the procedure meed to assess this ignition technique. The effectiveness of ignition technique is checked by comparing the proximity of the ignition envelope to the stability envelope of the afterburner. The tests have demonstrated city of this technique. The disadvantages of the currently used ignition13; systems have been brought out and it is shown that the pyrogenic ignition system possesses significant advantages over the established methods.
