Ale3D DDC Burn

ALE3 D can model the detonation, deflagration, and convective burn processes associated with the energetic response to thermal and mechanical stimuli of both high explosives and propellants.

  • Rocket Motor Impact

    NATO fragment impacting HPP rocket motor at 1.0 and 2.6 km/s. The PERMS (propellant energetic response to mechanical stimuli) model is used to predict the impact response of the propellant to the NATO fragment.


  • Convective Burning

    Modeling the convective burning of PBX-9501 as part of the HYDRA thermal explosion imaging experiments. Multi-velocity model coupled with chemistry enables simulations of the evolving deflagration of thermally-degraded material.
