In 2011, cocrystallization of energetic materials became a hot topic and pathway to overcome the energy−safety contradiction; especially for commercially attractive nitramines, it first preference researchers. The present review focuses on energetic−energetic four CL20, HMX, BCHMX, RDX, structural aspects these cocrystals, their influence thermochemical detonation properties. Cocrystallization has proven be crystal engineering technique achieve safety morphological suitability cocrystals (EECCs). Overall, in most cases, impact sensitivities EECCs are decreased, this is phenomenal change; however, needed adjust with properties slightly, negligible if coformer (EMs) properly chosen. There other notable variations morphologies packing crystals, including key such as relatively high density melting point. These changes occur due binding energy, trigger bond length, cohesive energy during cocrystallization. Researchers highly focused nitramines; earlier reported methods lacking selectivity scalability. When comes adoption industrial scale production EECCs, more difficult. We conducted thorough literature survey. Also we discussed about recently developed VPSZ coagglomeration method, which provides huge opportunity tune performance existing easy up level.

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.
