Effect of metal explosion foil on results of flyer initiating explosives

The initiating system using electrically exploded metal foils to accelerate small flyer can make the velocities of flyer to 4-5 000 m/s. The flyer can provide a high impact pressure to initiate explosives. Metal foil is an important element in the system of flyer initiating explosive. The time of metal foil explosion is about 1-2 mu s. When conduct time is long, the metal foil can't explosion and it will only be melt as a fuse. In order to ensure the work of metal foil normally, the metal foil thickness can be selected as 5 gm, the length and width of metal foil is 1 mmx 1 mm. By experimental testing, it is found that the time of metal foil damaged is 1.8 mu s and can meet the need of flyer initiating system.
