Energetic materials, essential for rocket propulsion, play a crucial role in aerospace systems. These materials lack sufficient safety assessments and pose significant risks to life infrastructure. The slow progress this field is hindered by prohibitively high experimental costs the inherently destructive nature of these experiments. This study aimed evaluate modeling-based assessments, primarily utilizing Lee–Tarver model. It specifically addressed threat posed shaped charges during transportation. Experimental analyses employed 50 mm JH-2 charges, targeting RDX-based formulation, since RDX widely used various motor propellant formulations. TNT was also enhance validation model findings. Various logistical configurations were explored, testing steel container walls ranging from 10 thickness reinforced mm, 60 65 steel. Comparative analysis with experiments accuracy model’s numerical predictions. Both simulations affirmed that protection suffices safe transportation formulations within storage box setups. Furthermore, emphasizes reliability most energetic while acknowledging certain limitations.

Aging behavior of pyrotechnic agents is a serious threat to the reliability practical application products, while multiple environmental factors make it challenging characterize aging mechanism agents. This paper explored process LA in four hygrothermal environments with morphology and structure analysis techniques. underwent three stages: rapid surface reaction H2O CO2, interior hydrolysis by H2O, CO2 lead oxides. The cavity structures formed during LA's structural evolution reduced its energy density, causing increased dissipation under mechanical stimuli preventing ignition. Further, reactions inert compounds resisted electrostatic ignition, leading agent failure. comprehensive study provided solid foundation for understanding multistress environments, offering valuable insights into safe storage handling.
