为探讨中心药管和径向药管爆炸抛撒对FAE爆轰特性及威力影响,通过高速录像、压电传感器和红外热像仪记录FAE静爆实验。获得两发50kgPO、1.5kg抛撒装药、两种爆炸拋撒作用下的云雾扩散、火球温度、冲击波超压数据。结果表明,采用中心药管和径向药管爆炸拋撒形成的云雾覆盖面积和起爆形态相差不大;后者在云雾和破片均匀性方面优于前者,火球温度比前者增益约12%,冲击波超压比前者增益约20%~35%.

In order to analyze the influence of cloud explosion characteristic and power by the central charge tube and multi-point explosive dispersion. Static explosion experimentation was recorded by fast kinematics analysis, piezoelectric sensor and infrared thermo-imaging measurement systems. The experimental data of cloud dispersion, temperature of blast fireball and overpressure of cloud zone of 50kg PO fuel and 1.5 kg dispersion charge of FAE devices by two kinds of igniting were obtained. It is shown that cloud area and ignition shape is similar to different dispersion form mentioned above. The uniformity of cloud and fragments of central charge ignition prevail over that of multi-point ignition. The temperature of the latter is 12% higher than that of the former. The overpressure of the latter is 20%~35% higher than that of the former.
