Nitramine Propellant Erosivity - III.

Abstract

This report is the third in a series on erosion measurements in a 37-mm blowout gun to compare the erosivity of propellants with RDX and HMX, denoted nitramines, with conventional double- and triple-base propellants. In these tests, a series of nitramine, triple-base, and double-base propellants were formulated with equivalent flame temperatures; three such groups of propellants were made with flame temperature of 2,700, 3,000 and 3,300 K. Closed-vessel measurements verified that the propellants manufactured at the LCWSL, Dover, NJ, conformed to thermochemical predictions made with the Blake thermochemical code. Erosion measurements were made at two rupture pressures. The charge weight of each propellant was adjusted to give a closed-bomb pressure slightly above the rupture pressure. The results of the tests showed the propellants with similar flame temperatures yielded similar erosion; propellants with higher flame temperatures always eroded more metal. These results are in agreement with the earlier reports that the nitramines behave as conventional propellants regarding gun wear.
