Abstract: PURPOSE: A plasma injector for igniting a propellant is provided to reduce the ignition delay time of a propellant by stably injecting high-temperature and high-pressure plasma to the propellant. CONSTITUTION: A plasma injector for igniting a propellant comprises an injector body(11), inner and outer electrodes(12,13), insulating units(18,19), a capillary tube(14), a metal wire(15), an ablation material(16), and a plug(17). The inner and outer electrodes and the insulating units are installed inside the injector body and transfer high-power pulse electric energy to the injector body. The capillary tube is formed in the inner center of the injector body and generates plasma from the electric energy. The metal wire crosses the capillary tube. The ablation material is installed in the edge of the metal wire. The plug seals one end of the injector body.
