摘　　要：以常用点火材料NC(硝化棉)、BP(2#小粒黑)和奔萘药作为点火药,考察点火药对RGD7A基三层片状硝胺发射药的点火能力。以特征点火药量、点火延迟时间及点火压力为点火性能判据,通过点火性能对比试验,发现奔萘药更适合作为RGD7A基三层药的点火药。进一步通过密闭爆发器试验证明,采用奔萘药作为RGD7A基三层药的点火药,可有效提高RGD7A基三层药的点火同时性,效果明显优于NC和BP。Selecting commonly used ignition materials such as nitro-cotton（ NC）,BP（ 2#small black powder） and benzene naphthalene drug,the ignition performance of the powders on RGD7 A based three layers gun propellant were studied. It was found that benzene naphthalene drug is suitable for the RGD7 A based three layers gun propellant by means of experiments on ignition performance characteristic of ignition charge,the ignition delay time and the ignition pressure.And it also shows that,in closed bomb test,benzene naphthalene drug can effectively improve the simultaneous ignition of the RGD7 A based three layers gun propellant,which is superior to the other two ignition powders（ NC and BP）.
