In the present work it is found that the pyrotechnic composition VS?2 can be initiated with flash lamps IFC?500 and EVIS. VS?2 pyrotechnic composition contains 90％ of mercury(Ⅱ)5?hydrazinotetrazolate perchlorate and 10％ of optically trans?parent copolymer of 2?methyl?5?vinyltetrazole and methacrylic acid(PVMT). We have found that the flash lamps make it possi?ble to initiate combustion of VS?2 composition with its transition to detonation both in cylindrical charges placed in brass caps of 5 mm diameter and 2 mm high,and film charges with 10 mm×80 mm in size and surface weights of 60 mg·cm-2 and 90 mg·cm-2, showing ignition delay times 10 μs and 3 μs,respectively. We also measured detonation velocities for VS?2 composition film charges,which were 4375-4505 m·s-1(of the charge being surface mass 60 mg·cm-2)and 4221-4281 m·s-1(of the charge be?ing surface mass 90 mg·cm-2)and their blasting action on the aluminum plate. The depths of the normal shock wave imprints at the charge?barrier interface were 0.6-0.7 mm(for surface mass of the film charges 60 mg·cm-2)and 1.2-1.3 mm(for surface mass of the film charges 90 mg·cm-2).
