DISTRIBUTION OF THE FIRING ENERGY FOR THE SQUIB MK 1 MOD 0

Abstract

Neither the log-normal nor the log-logistic provides an adequate fit over the entire range of the Squib Mk 1 Mod 0 data. Using unbiased estimates of firing probabilities, both of these distributions fit the lower 95% of the firing sensitivity data reasonably well. The log-normal gives a slightly better fit to these data. It is illustrated that the upper 5% of the firing energies generally contribute a negligible amount to the probability of an accidental firing. These data indicate that the log-normal distribution provides a satisfactory approximation when calculating the probability of an accidental firing. Since both the log-normal and log-logistic fit the Squib Mk 1 Mod 0 firing data about equally well, use of the log-normal distribution is recommended in HERO computations where the distribution of the induced currents also must be considered since this leads to a simpler procedure for estimating accidental firing probabilities.
