Analytical Assessment of the Suitability of a Liquid Explosive Substitute for Shaped Charge Testing
Technical rept. April-May 1991
SYSTEM PLANNING CORP ARLINGTON VA
Pagination or Media Count:
In this analysis, a 95 nitromethane NMe and 5 diethylamine DEA liquid explosive is substituted into a BRL 3.3 inch 42 degree conical copper lined charge. The original charge is Octol loaded. Since NMe is less energetic, it is expected to give a reduced jet tip velocity, less jet mass, and lower overall jet kinetic energy. This would naturally follow from the use of a lower energy density explosive. The liquid explosive load will then be modified by a combination of liner subcalibering and detonation front wave shaping to investigate how the original jet characteristics may be recovered.
