HL-10 explosive is an aluminized explosive based on RDX. In order to investigate the safety characteristics of HL-10 for bullet impact test, 12.7 mm bullet was used to impact HL-10 charge. Experimental results show that there is no significant reaction or burning resulted from these bullet impact tests, so the impact sensitive of HL-10 for bullet impact test is defined as the first grade. The calculation modes and methods of bullet impact tests were established. The three-dimensional numerical simulations of the bullet impact tests were conducted. Good agreement was found between the calculated results and the experimental results. In addition, the responses of HL-10 to different bullet impact velocities were analyzed. The calculated results can provide a theoretical basis for the analysis of explosives safety evaluation. To further verify the calculation model and method, the bullet impact test calculation for America PBX-9404 explosive was conducted. The results show that, PBX-9404 explosives would be detonated at 850 m/s impact velocity for the same calculation mode, which are consistent with Neff and others experimental results.
