摘要:
以相同工艺制作类石墨桥膜点火桥,对其进行蘸药等处理，形成点火头结构;升降法试验得到不同激发条件下50%发火时的电流或电压，并验证其发火可靠性；测试点火头的响应状态，得到裸桥状态下类石墨桥膜对不同能量输入的响应。以相同方式制作桥丝式点火头，得到发火参数与电压、电流特性。涂覆有150目下叠氮肼镍(NHA)的类石墨桥膜，99%恒流发火电流为325.65 mA；99%恒压发火电压为2.43 V；在电容47 μF条件下99%脉冲发火电压为10.45 V。同样蘸药的桥丝式点火头，99%恒流发火电流为89.61 mA；在电容47 μF条件下99%脉冲发火电压为4.72 V。对比发现，类石墨桥膜点火头在使用钝感药剂时可满足0.99（0.90置信度下）可靠度要求。
Abstract:
Graphite-like film ignition bridges made by the same manufacturing process were treated with dipping and other treatments to form the ignition head structure. Lifting method was used to obtain the 50% ignition current or voltage under different excitation conditions, and to verify the ignition reliability. Response state of the bare bridge ignition head was tested to obtain the different response performance under the different energy input between the graphite-like membrane bridge and the bridge wire. The bridge wire ignition head made by the same manufacturing process was also tested under the same dipping conditions. Its ignition parameters, current and voltage characteristics were also obtained. For graphite-like bridge membrane coated with NHA under 150 mesh, it has a 99% constant ignition current of 325.65 mA, a 99% constant ignition voltage of 2.43 V, and a 99% pulse ignition voltage of 10.45 V under 47 μF. The bridge wire ignition head treated with same dipping has a 99% constant ignition current of 89.61 mA, and a 99% pulse ignition voltage of 4.72 V under 47 μF. Comparison shows that, with the application of insensitive chemicals, graphite-like bridge membrane ignition heads can achieve a reliability of not less than 0.99 (under 0.90 confidence) in practical use.
