Energetic Igniters Based on Al/CuO/B/Ti Reactive Multilayer Films
An energetic igniter is introduced and prepared by integrating Al/CuO/B/Ti reactive multilayer films onto glass substrate. The structure of igniter is similar to a capacitor, which may place an electric field across the igniter and allow the instantaneous large-current to drift through the igniter. Firing characteristics is achieved by using a 470μF capacitor discharge firing set. It is found that the igniter has several merits such as insensitivity, exothermic reaction of the films and strong combustion flame with ejected products. A systematic temperature diagnosis model based on spectroscopy method is presented and used to obtain the plasma temperature and its duration. The peak plasma temperature of the igniter is about 5400K, and the duration where temperature over 4000K is about 0.5ms, when the igniter is discharged in 60V. These results indicate that it is possible to fabricate insensitive and reliable igniters by utilizing Al/CuO/B/Ti reactive multilayer films.
