Abstract: The purpose of this project is to measure if differing amounts of potassium perchlorate, KCIO4, mixed with shotgun powder has an effect on burn rate. The experiment was videotaped and the duration of burn time for each amount used was recorded. KClO4, amounts ranging from .2g to 2g, were added to 4g of shotgun powder. A steel pipe that is ½ inch wide and 6 inch, which is welded vertically to a steel plate base was used for confinement. Ignition occurred from the top down. The hypothesis that was accepted is that the concentration of KClO4 will accelerate the burn rate of smokeless flake powder.

(B. Berger J. Bramme, 1997) to date no study was found that measured the burn rate of KClO4 and shotgun powder.

Research question: Does the concentration of potassium perchlorate KClO4 accelerate the burn rate of smokeless double based flake powder? (Alliant: Green Dot brand)
: Null hypotheses: No, the concentration of potassium perchlorate, KClO4 , will not accelerate the burn rate of smokeless flake powder.
: Alternative hypotheses: Yes, the concentration of potassium perchlorate, KClO4, will accelerate the burn rate of smokeless flake powder.

Materials: * Potassium Perchlorate (Pyropak brand) * Alliant, Green Dot double-base smokeless flake powder * Digital scale * Butane lighter * ½ inch wide, 6 inch long steel pipe welded vertically onto steel plate * Video camera * 2 glass mixing bowls * Small metal spoon

Procedures: * KClO4 (Pyropak brand) was measured in .2g increments using a digital scale. There was not a sufficient amount of KClO4 for the entire scale, so increments 1.4, 1.6, 1.8 were omitted. The KClO4 was added to 4 grams of Alliant, Green Dot double-base smokeless flake powder in a glass bowl. The resulting mixture was then mixed by spoon for approximately 1 minute. The mixture was transferred by funnel into a ½ inch wide, 6 inch long
