Abstract:

As part of the Naval Explosives Safety Improvement Program NESIP, two series of tests have been conducted to determine the maximum TNT equivalence of Naval propellants. Airblast and detonation velocity measurements were made on M26 and NACO 5-inch propelling charges, MK 10 3.25 in., MK 16 5 in., MK 40 2.75 in., MK 58 SPARROW, MK 37 ASROC, MK 27 TARTAR, MK 30 STANDARD rocket motors, and TNT cylinders. The Mk 40 and MK 37 motors detonated high order and had a TNT equivalence of 70-75. The other applications had TNT equivalencies ranging from 5 to 50. Recommendations are also made about possible revisions to OP-5. Instead of the 25 percent equivalency now used for guided missile propellants, 100 percent is recommended for double base and compositedouble base materials, 50 percent for composite materials, and 125 percent for high energy propellants.
