Examination of the Thermal Ignition of M30 Propellant by Residual Steel Fragments
Abstract
We report the results of a set of experiments designed to determine the threshold ignition striking velocity (Vs) of fragment simulating projectiles (FSP) that perforate a plate of titanium armor and come to rest in a bed of M30 propellant. A subset of experiments, which focus on an 830 grain (gr) FSP shot through 0.25 in. thick titanium, are modeled using physics-based computer codes. The modeling approach employs two codes in series, an Eulerian shock-physics code (CTH) to model the armor perforation event and a Lagrangian hydrocode (LS-DYNA) to model the thermal conduction between the FSP and propellant. The computer modeling was designed in the interest of creating predictive methodology for evaluating survivability and lethality. The research was funded by the U.S. Army Research Laboratory (ARL) Director's Research Initiative.
