Abstract
The present invention is a pyrotechnic time delay system that is improved over prior-art designs. Specifically, the system described herein comprises at least one delay element. The delay element or delay dements each have an input charge, a delay composition, and an output charge. Both the input charge and the output charge are igniter compositions and are comprised of the same components despite having different functional goals. The input charge and output charge compositions preferably contain titanium, manganese dioxide, and polytetrafluoroethylene. The delay composition may be modified from current formulations to include manganese and manganese dioxide, or tungsten and manganese dioxide. The system disclosed herein may be comprised of one delay element, or it may be modular wherein multiple delay elements are connected in series.
