The ignition principle and the characteristics of the exploding foil slapper are introduced. The integration design for the slapper igniter with the ignition composition cup is used to make the exploding foil igniter. The results of the exploding foil igniter performance test and successful to rocket motor ignition composition show that the igniter cannot be ignited by 3 A direct current in 5 min and has better capabilities in resisting static electricity,radio-frequency and electromagnetic interference. The rocket moter ignition composition can be ignited by the exploding foil igniter safely and reliably.
