Abstract:

The effect of confinement on the initiation of low-velocity detonation LVD was studied with particular emphasis on the confinement strength and charge length. Using 1,2-bisdifluoramino-2-methylpropane IBA as a model compound, it was found that there was a slight increase in the apparent LVD gap sensitivity when the ratio of charge length L to the charge diameter D was increased threefold. Studies with both IBA and ethyl nitrate indicate that for these compounds the use of a witness plate as an LVD detector causes only a slight increase in the apparent LVD gap sensitivity. Work was also concentrated on refining previous shock temperature calculations on unreacted carbon tetrachloride and nitromethane. In particular, a more satisfactory form of the Hugoniot, was incorporated. The decomposition of vibrationally excited CH3NF2 was studied, and through appropriate RRKM analysis the rate parameters for CH3NF2 yielding 2HF HCN were determined. Author
