Abstract
The minimum energy, delivered in a 3 ms interval, just sufficient to ignite 1 cm 2 of explosive has been investigated for the cases of trinitrotoluene, tetryl, cyclo-trimethylene trinitramine (RDX), pentaerythritol trinitrate (PETN), blasting gelatin, lead azide, and lead styphnate. Absolute values, which may be somewhat in error due to extensive corrections necessary in interpreting experimental data, range from greater than 0·4 cal/cm 2 for TNT to less than 0·1 cal/cm 2 for lead styphnate. Relative values are considered more reliable since errors in data analysis tend to cancel. A device is described for generating hot gas by adiabatic compression, together with experimental and analytical techniques for determination of ignition energies.
