Abstract: Presents a simple and useful self-sustained catalyst ignition device according to the keymotor effecting catalyst ignition. This device is applied with high-resistance as the catalyst-bed.Theignition temperature,the ignition energy and the ignition delay are reduced when the catalyst-bed iselectrically heated directly.As a supplementary ignition device of ramjets or turbojets this achievementin scientific research has a bright future.

Key words: Ramjet engine;Turbojet engine;Ignition device;Catalytic ignition;Lowtemperature ignition
