SENSITIVITY FUNDAMENTALS.
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-bis(difluoramino)-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)
