Abstract Taking copper azide microcharge as research object, PVDF piezoelectric sensor was used to test the detonation pressure of and titanium flyer driven by explosion respectively. The effect flyers on output performance investigated. results shown that: different structure parameters affected charge weight, weight directly pressure. drive is much greater than microcharge. Titanium explosion...
