The two types of flyer were designed to study short duration pulse shock initiation characteristics of ultrafine 2, 6-diamino-3, 5-dinitro-pyrazine-1-oxide(LLM-05). The firing testing of ultrafine LLM-105 is implemented by D-optimal method based on analysis of flyer velocity. It is found that the flyer velocity is increasing as increasing pulse current. The velocity is sensitive to current variety for large dimension flyer by contrasting small dimension flyer. The inferior velocity consistency for large flyer exists, which has the relationship with air resistance. The air resistance is increasing with improvement of flyer dimension. The 50% firing current, of ultrafine LLM-105 is 2.14 kA by small dimension flyer, which is almost equal to initiating threshold of HNS-Ⅳ. It is indicated that ultrafine LLM-105 would be used for initiation explosive at slapper detonator. The LLM-105 explosion system will satisfy the development trend of slappde detonator, namely, desensitization, low input energy, and so on.
