The increasing demand of modern warfare on the low collateral damage and the flexibility of ammunition makes the explosion equivalent be the research focus. Probe method and fragment recovery method were used to investigate the output energy of press fitting 8701 explosive warhead with ignition loading at various quantities. Results show the easy transition of 8701 explosive from burning to detonation in warhead. As the charge quantity increases, especially within the range of 0.22.0g, the transition was accelerated accompanying with larger warhead generation energy and higher shell fragmentation quality. When the charge quantity increases to 5.0g, the warhead charge reaches to the extent of direct detonation. Results of the study also show that ignition composition quantity control can be used in the quality adjustment of the warhead power.
