Dependence of the TNT Equivalent of an Underwater Explosion on the Content of Aluminum Hydride in an Energy Material

The results obtained show that the addition of aluminum (Al) and aluminum hydride (AlH₃) to an explosive significantly increases the heat of an explosion (HE) and the TNT equivalent (TE) of an underwater explosion. The compositions with AlH₃ are inferior to their Al-containing counterparts in the HE. However, the formulations with AlH₃ have the advantage in terms of the number of moles of gaseous products. Replacing Al with AlH₃ weakly affects the TE in terms of the energy of a gas bubble, while the TE in terms of the energy of a shock wave is higher for the mixtures with AlH₃. The latter is especially noticeable in the case of an explosive with a positive oxygen balance. However, the compositions with AlH₃ are inferior to the Al-containing mixtures in terms of volumetric TE.
