Abstract:
The ignition energy requirements for a range of pyrotechnic compositions of interest in both Australia and the United States have been measured experimentally using a 400 W CO2 laser operating at 10.6 microns. The effects of several physical and chemical variables were determined on the time to ignition and ignition energy. The materials examined include a gasless delay, igniter compositions, a primer composition and a range of colored smoke compositions. The experimental data serves as a useful probe into ignition mechanisms, and may prove of value in the design of practical ignition systems.
