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.

Abstract: A simplified method for synthesizing boron phosphide at high yields. The method requires mixing of boron phosphate and magnesium metal without diluents into a homogenous mixture, loosely packing the mixture at less than 20,000 psi and igniting the mixture using an energy input that is not greater than 20% of the reaction energy output to create a self-propagating high-temperature reaction wherein the boron phosphate and magnesium metal is completely burned during the reaction to synthesize boron phosphide at high yields.

Abstract: System and methods for simultaneous characterization of tracer light output and velocity by arranging a plurality of photodetectors along the flight path of the tracer and transmitting the detected light output over large distances using an array of analog/digital converter units arranged to correspond to each photodetector. The system can be scaled and configured to operate and control the photodetectors from a remote location.

Abstract: A novel pyrotechnic composition comprising nanostructured crystalline boron phosphide and oxidizer such as potassium nitrate wherein the crystalline boron phosphide is synthesized by a self-propagating high-temperature reaction. The nanostructured crystalline boron phosphide and oxidizer pyrotechnic composition unexpectedly emits smoke and green flame upon ignition.
