“…(iii) Scientists from Poland [104] have recently reported some spheroidal NTO & FOX‐7 based formulations on laboratory scale and studied these formulations for various properties relevant for IMs. Based on these properties, it was claimed that FOX‐7 can be used in low sensitivity melt‐cast explosive formulations and Comp FOXN is promising as a main charge filling destined for IMs.…”

High Energy Materials (HEMs) is a generic/umbrella term which is used for explosives, propellants & pyrotechnics and form an integral part of almost all weapon systems. A large number of HEMs have been reported in the literature in last few decades. This review paper discusses these HEMs in the light of a new classification of explosives proposed by Agrawal: Thermally stable or Heat‐resistant explosives, High performance (high density & high velocity of detonation) explosives, Melt‐Castable explosives, Insensitive high explosives (IHEs), Energetic binders & plasticizers and Novel energetic materials synthesized with the use of dinitrogen pentoxide (N2O5) technology. This review also critically examines these HEMs from the angles of scalability, processability, safety, reliability and performance in order to ascertain their potential for applications. In the end, problems associated with the use of currently available energetic materials & their likely solutions and areas for further research are also highlighted.

To investigate the detonation characteristics of a new aluminized DNAN‐based melt‐cast explosive RDA‐2 (containing DNAN (2,4‐dinitroanisole), HMX (cyclotetramethylene tetranitramine) and aluminum), a series of cylinder tests were conducted. The LiF (lithium fluoride) explosive of a similar formulation was also tested to study the influence of aluminum on the detonation characteristics of RDA‐2. The cylinder wall expansion velocities were recorded by Photonic Doppler Velocimetry (PDV). From the experimental data, the detonation velocity, the Gurney energy, the detonation energy, and the CJ pressure of the explosives were calculated. Both the detonation velocity and CJ pressure results indicate that the aluminum seems to have no significant influence on the chemical reaction zone of RDA‐2. The experimental data shows that a large amount of aluminum reacts behind the CJ point. Finally, the parameters of the Jones‐Wilkins‐Lee (JWL) equation of the state of the detonation products were determined.

Study on the Effect of NTO on the Performance of HMX-Based Aluminized Cast-PBX

3-Nitro−1,2,4-triazol−5-one (NTO) is an explosive with broad application prospects. To study the effect of NTO content on the properties of HMX-based cast-PBX (polymer bonded explosive), five different HMX/NTO-based cast-PBXs were prepared and characterized by experiments and simulations. The results show that the addition of NTO is beneficial to reduce the mechanical sensitivity of cast-PBX, but will reduce the energy level of cast-PBX. We then found that with the increase in NTO content, cast-PBX showed a trend of first increasing and then decreasing in terms of mechanical properties, specific heat capacity (Cp) and thermal conductivity (λ). In addition, we found that the Gurney energy (Eg) of N30 is 2.31 kJ/g. Finally, the increase in NTO content greatly improves the thermal safety performance of the cast-PBXs, and numerical simulation of slow cook-off can be used as one reliable method to obtain the ignition location, ignition temperature and the transient temperature distribution.
