“…Generally, scientists are concerned about the explosives' thermochemical properties and the relationship between the formula and detonation performance, such as empirical formulas of detonation [2][3][4][5] and well-known equations of state (EOS) of detonation products: BKW-EOS [6], JCZ-EOS [7], KHT-EOS [8], and JWL-EOS [9]. On the other hand, they are usually more focused on the underwater damage effects of explosives [10][11][12][13][14][15][16][17][18][19][20] and there is a connection between formula, detonation performance and underwater damage effect. Therefore, research on the exact relationship between the damage effect of aluminized explosive and underwater energy output structure is necessary to optimize the design of charge for underwater weapons.…”

The performance of detonation and underwater explosion (UNDEX) of a six-formula HMX-based aluminized explosive was examined by detonation and UNDEX experiments. The detonation pressures, detonation velocities, and detonation heat of HMX-based aluminized explosive were measured. The reliability between the experimental results and those calculated by an empirical formula and the KHT code was verfied. UNDEX experiments were carried out on the propagation of a shock wave and a bubble pulse of a 1 kg cylindrical HMX-based aluminized explosive under-water at a depth of 4.7 m. Based on the experimental results of the shock wave, the coefficients of similarity law equation for the peak pressure and attenuation time constant of shock wave were in acceptable agreement. The bubble motion during UNDEX was simulated using MSC.DYTRAN software, and the radiusÀtime curves of bubbles were determined. The effect of the aluminum/oxygen ratio on the performance of the detonation and UNDEX for an HMX-based aluminized explosive was discussed.
