Abstract : A vertical detonation tube was used to study the blast initiated detonation of various liquid fuels (organic nitrates and nitro compounds), including some monopropellants, in a few different oxygen-nitrogen atmospheres. The fuels tested included n-propyl nitrate, nitropropane, nitromethane, and decane. All fuel drops were of the same size and a range of mixture ratios were tested. Attention was given to the influence of diaphragm thickness, ignition point location in the driver, and charge gas equivalence ratio in the driver. Experiments were also conducted in a sectored chamber, wherein cylindrical blast waves were generated by a condensed explosive and electric detonators. (Modified author abstract)
