A fuze delay function can be achieved in two ways, either electrically or chemically. An electrical fuze delay function uses an in-line electronic S & A, while a chemical delay employs an out-line system. Primary explosives with out-line fuze electronic delay present a safety hazard. Conversely an in-line electronic delay, thus safer, makes use of secondary explosives, which are susceptible to shocks from the projectile launch environment. The object of this program is the realization of a fuze delay function by either using a deflagrating secondary or pyrotechnic explosive. These explosives, when electrically initiated will accelerate a plate (known as a flyer) at supersonic speeds. The ensuing shock wave from the plate will detonate an output secondary explosive. To determine the length of attainable delays, several initiating secondary explosives will be investigated in various design configurations. The most promising design configuration will be fabricated and tested. A general application will be brought forth.
