  • To verify impact safety and implosion power of a composed charge, the drop hammer tests and implosion power experiments were conducted. The results show that critical height of the single thermo-baric explosive is 2.2 m under loading of 400 kg hammer, while the composed charge did not ignite under height from 2.2 m to 2.7 m, which means that the composed charge holds a better impact safety property. Peak overpressure of the composed charge was 61.9% of the single thermo-baric explosive, the impulse of the composed charge was 99.4% of the single thermo-baric explosive, and the peak quasi-static pressure of the composed charge was 94.5% of the single thermo-baric explosive. Considering energy release characteristics within a limited space, it is more suitable to use peak quasi-static pressure as an evaluation standard. The test results show that implosing energy release characteristics of the composed charge is almost the same as the single thermo-baric explosive.
