专利汇可以提供Ignition circuit for projectile fuses专利检索,专利查询,专利分析的服务。并且A projectile with an electrically ignitable fuse is provided with a control circuit in which piezo electric cells are provided which develop a potential upon acceleration of the projectile and then develop a reverse potential upon relaxing of the acceleration on the projectile when it emerges from the firing weapon. The piezo electric cells are serially arranged and connected thereacross is a pair of condensors, the juncture of which is fastened to the juncture of the cells with one capacitor charging during the acceleration period of the projectile and the other charging during the relaxing period. A resistor connected across the capacitors provides for reversing of the charge on the one capacitor and which reversing triggers a control circuit. The control circuit releases the charge from a third capacitor which is charged by one of the cells during the relaxing period thereby to ignite the fuse. An impact control source of voltage is also provided for igniting the fuse upon impact of the projectile.,下面是Ignition circuit for projectile fuses专利的具体信息内容。
