Abstract
|
Pyrotechnic delays are used in commercial and military items requiring a time delay between two energetic events. For example, US Army hand- held signals (HHS) use a delay element to properly sequence the expulsion of illuminating rounds at the rockets' apex. Many military delay formulations contain barium, lead, chromates, and perchlorates. The US Army is reformulating pyrotechnic items to remove environmentally hazardous materials. In this paper, new environmentally benign formulations are described. The delay time of the new system is easily tunable. These compositions will consistently function in aluminum housings which is generally difficult for delay compositions due to extreme thermal losses that can cause quenching.
