    Abstract
  • In order to accommodate to the needs of micro-explosive train in MEMS fuze, this paper carried out a specific study about the influence of charge height on the output detonation pressure in micro-detonator. The charge diameter is 0.9 mm, total height is 3 mm. The charge ratio of primary explosive and high explosive was to be changed. The output detonation pressure was measured by manganin piezoresistance method. In the micro-detonator, the critical height of primary explosive PbN6 is 0.36 mm. When the primary explosive PbN6 height is 1.65 mm, the micro-detonator has the maximal output detonation pressure 10.3 GPa. When the primary explosive PbN6 height is less than or more than 1.65 mm, the high explosive HMX height is less than or more than 1.35 mm, and the output detonation pressure of the micro-detonator is reduced. The range of the primary explosive PbN6 and the high explosive HMX is 0.69～2.26.
