The influence of aluminum and ammonium perchlorate dispersion on characteristics of the laser ignition
Egor Forat, Valery Medvedev, Vladimir Tsipilev, and Alexey Yakovlev


Laser ignition of the stoichiometric mixtures based on aluminum and ammonium perchlorate has been experimentally studied. A laser with a radiation wavelength of 1.06 μm and a pulse duration of 0.8 ms was used to initiate ignition. The ignition thresholds were determined for samples with different degree of dispersion of both aluminum and ammonium perchlorate. The samples were exposed to laser radiation in confined conditions in order to prevent gas pressure relief. The difference in the mixture sensitivity to laser radiation is discussed within the theory of thermal ignition and light scattering.
