Abstract

In order to explore the effect of semiconductor bridge shape and size on the performance of Al/CuO energetic initiators, two shapes and two sizes of bridges were designed and studied during capacitor discharge. The results show that there is a delay between the V-angle and other parts of the V-shaped bridge. Both V-shaped and miniaturization designs were capable to accelerate the process and reduce the required function energy. However, when initiating explosive was coated on the initiators, the ignition time of explosive on initiators with V angles but different sizes is quite close.
