Abstract:

Thousands of fuzeheads were fired by two methods i.e., constant current pulse, and capacitor discharge, with the object of establishing sensitivity criteria of the range employed for operation of explosive motors. Extrapolation of energy characteristics to zero application time generally indicate values of basic energy lower than those found when using capacitor discharge circuits. The design of reliable firing circuits for use in service equipment requires the energy available to be at least twice the values for 100 initiations, but when initiation is to be achieved by very short pulses, i. e., less than 5.0 milliseconds, or by capacitor discharge, a factor of three is more appropriate.
