A COMPARISON OF EXPLOSIVES IN A CONICAL SHOCK TUBE
Abstract
Experiments were performed to determine whether or not the 180-foot conical shock tube facility located at the Naval Ordnance Laboratory can be used to determine free-air equivalent weights for several test explosives. The explosives tested were H-6, TNT, pentolite, and TNETB. The rankings of explosives as determined in the CST agree with the rankings in free air. Numerical values of equivalent weights vary with pressure, but even so the values obtained in the CST do not reproduce the single number usually cited for equivalent weights determined in free air using conventional methods. The variations are believed to be real and presently are thought as likely to represent an uncertainty in the conventional concept of equivalent weight just as much as a fundamental limitation of the conical shock tube. Analysis continues to resolve these differences.
