    • 摘要: 为了研究由桥箔、飞片和加速膛所组成的换能组件对爆炸箔起爆器(EFI)发火性能的影响,达到降低发火阈值的目的,利用ANSYS/AUTODYN软件,模拟了桥箔驱动飞片起爆六硝基芪(HNS-Ⅳ)的过程.研究了桥箔厚度对飞片速度的影响,探究了桥区宽度、飞片材料(有机玻璃、陶瓷和聚酰亚胺)、飞片厚度和加速膛长度对EFI发火阈值的影响.结果表明,减小桥区宽度有利于降低爆炸箔起爆器的发火阈值.在输入电压相同的条件下,2 μm厚度的桥箔驱动飞片速度最大;爆炸箔起爆器发火电压随着飞片厚度的增加先降低后增大,当厚度为10μm时发火电压最低;相比于0.225 mm、0.250 mm和0.275 mm加速膛,用0.125 mm加速膛时发火电压最低,说明减小加速膛长度有利于降低爆炸箔起爆器的发火阈值;在加速膛孔径确定的情况下,“无限型”加速膛发火电压低于“有限型”加速膛.聚酰亚胺力学性能好、发火电压低、撞击动能小,优于其它两种材料(有机玻璃和陶瓷).%To study the influence of the transducer component composed of bridge foil,flyer and accelerating chamber on the exploding foil initiator (EFI) ignition performance and achieve the goal of reducing the ignition threshold,ANSYS/AUTODYN software was used to simulate the process that bridge foil driven flyer to detonate HNS-Ⅳ.The influence of bridge foil thickness on flyer speed was studied,and the influences of bridge area width,flyer material(organic glass,ceramic and polyimide),flyer thickness and accelerating chamber length on EFI ignition threshold were investigated.Results show that reducing the width of bridge area is helpful to reduce the ignition threshold of exploding foil initiator.Under the same input voltage,the speed of flyer driven by bridge foil with thickness of 2 μm is maximum.The ignition voltage of exploding foil initiator decreases firstly and then increases with the increase of flyer thickness,and the ignition voltage is lowest when the thickness is 10 μm.Compared with 0.225 mm,0.250 mm and 0.275 mm accelerating chamber,ignition voltage of 0.125 mm one is lowest,so reducing the acceleration chamber length is beneficial for reducing ignition threshold of exploding foil initiator.Under the condition of determinig the accelerating bore aperture,"infinite" accelerating chamber is better than "finite" accelerating chamber for reducing firing voltage of EFI.Polyimide has better mechanical properties,lower ignition voltage and lower kinetic energy compared with other two materials (organic glass and ceramic).

    • 摘要: To study the effect of environment oxygen content (oxygen volume fraction) at different altitudes on the combustion characteristics of aluminum-magnesium fuel-rich propellant,the laser radiation ignition was used.The ignition and combustion process of the propellant was recorded by a high-speed camera,and the surface temperature and flame temperature of the propellant were measured by an infrared thermometer.The effect of environment oxygen content and pressure on the ignition process,flame temperature and burning rate of the propellant was investigated.The results show that gas phase reaction of propellant ignition occurs mainly in the diffusion zone of propellant thermal decomposition products and environment gas,and the first flame is away from the propellant surface when the environment oxygen content is higher than oxygen content in thermal decomposition products,but the distance between the diffusion zone and the propellant surface decreases as the pressure increases.The flame temperature is in linearly positive proportion with the environment oxygen content and pressure.The burning rate of aluminummagnesium fuel-rich propellant increases with the increase of pressure and environment oxygen content and the effect of them on burning rate is accord with B-number theory,the pressure is the main factor affecting the burning rate,however,as the pressure increases,the effect of pressure on the burning rate is relatively reduced.The burning rate sensitivity coefficient ratio of pressure and environment oxygen content is decreased from 200 to 40 when pressure is increased from 0,1 MPa to 1.5 MPa.%为研究不同海拔处大气氧含量(氧体积分数)变化对铝镁贫氧推进剂燃烧特性的影响,采用激光辐射点火,使用高速摄影仪记录推进剂的点火与燃烧过程,并利用红外测温仪测量推进剂的表面温度及火焰温度,研究了环境氧含量与压力对推进剂的点火过程、火焰温度和燃速的影响.结果表明,环境气体氧含量高于推进剂热解产物中氧含量时,点火气相化学反应主要发生在推进剂热解产物与环境气体的扩散区,初现焰远离推进剂表面,但随着压力增加,扩散区与推进剂表面之间距离减小;火焰温度与环境氧含量和压力线性正相关;压力与环境氧含量增加时,铝镁贫氧推进剂燃速增加,压力和环境氧含量对铝镁贫氧推进剂燃速的影响符合B数理论,压力是影响推进剂燃速的主要因素,但随着压力增加,压力对燃速的影响相对减小,压力从0.1 MPa增加到1.5 MPa时,压力和环境氧含量的燃速敏感系数比从200下降到40.

    • 摘要: 针对半导体桥小型化带来的点火可靠性问题,制备了复合半导体桥,采用高速存贮示波器对其在22 μF电容不同充电电压下的电爆过程进行了研究,并与多晶硅半导体桥的电爆性能进行了对比.结果显示:在电爆过程爆发前,复合半导体桥和多晶硅半导体桥的电爆过程基本一致;爆发后特别是在高压时(50 V),与多晶硅半导体桥相比,复合半导体桥上电流下降缓慢,爆发所需时间稍偏长,作用于等离子体上的能量稍多;爆发后3 μS内,复合半导体桥作用于等离子体上的能量增加较多,因此复合半导体桥点火可靠性更高.复合半导体桥上金属薄膜的存在是造成上述结果差异的原因.

    • 摘要: 为兼顾固体火箭发动机水射流清理工艺的安全性、高效性、环保性,在水射流清理实验和废水收集实验的基础上,以清理作业中推进剂质量损失速率、废水产生速率为优化目标,以射流压力、靶距、喷嘴直径、单次清理时间为变量并加以约束条件,建立了固体火箭发动机水射流清理工艺的多目标优化方法。利用代理模型技术建立了推进剂质量损失速率的代理计算模型和废水产生速率的理论计算模型,使用非支配排序遗传算法( NSGA-Ⅱ)求得了 Pareto 优化解集。该优化解集可为不同情况下的水射流清理工艺设计中推进剂质量损失速率和废水产生速率的匹配提供多种方案。用推进剂质量损失速率和废水产生速率的最佳匹配,由HTPB 推进剂单位质量损失所造成的废水产生量仅为14.25 mL·g -1。%To achieve a balance among safety,efficiency and environment-friendliness of waterjet cleaning process of solid rocket motor,on the basis of waterjet cleaning experiments and wastewater collection experiments,a multi-objective optimization meth-od for waterjet cleaning process of solid rocket motor was established with propellant massloss rate and wastewater generation rate as the optimization objectives,and waterjet pressure,target distance,nozzle diameter and single cleaning time as the variables with constrained conditions. The calculation models of propellant massloss rate and wastewater generation rate were established with agent modeling technology,and Pareto optimal solution set was obtained by the non-dominated sorting genetic algorithm (NSGA-Ⅱ). Results show that the optimal solution set can offer a variety of programs for the matching between propellant mass-loss rate and wastewater generation rate in waterjet cleaning process design under different conditions. With the best matching between them,the wastewater production caused by HTPB propellant′s unit massloss is only 14. 25 mL·g -1 .

    • 摘要: The radio frequency( RF)sensitivity of semiconductor bridge( SCB)initiator can be improved by negative temperature coefficient( NTC)thermistors and temperature is the key factor for the protection effect. In order to analyze the influence of NTC thermistors on SCB electro-explosive performances at different environment temperature,constant current(1A)was forced to flow through igniters for 300 s at room temperature(25 °C)and high temperature(70 °C). Results show that about 59% current of small size SCB( S-SCB)is shunted by NTC thermistor at 25 °C,and reaching the maximum(63%)at 70 °C. Furthermore,with capaci-tor discharge experiment,the electro-explosive performances of the SCB initiators in parallel with NTC thermistors were discussed at above temperatures. Results indicate that burst time and consumption energy of large-SCB( L-SCB)initiators have no significant change at two temperature. But,as for S-SCB,burst time grows from 5. 94 μs to 7. 18 μs,and consumption energy reduces from 0. 388 mJ to 0. 178 mJ when temperature ranges from 25 °C to 70 °C.%温度是影响火工品电磁防护其防护效果的主要因素,负温度系数( NTC)热敏电阻用于半导体桥( SCB)能有效提高其射频感度。采用恒流激励和电容放电两种实验,对不同环境温度下 NTC热敏电阻对 SCB性能的影响规律进行了研究。通过1 A 5 min恒流激励实验,分析了室温(25°C)和高温(70°C)时 NTC热敏电阻的并联分流情况;25°C时 NTC热敏电阻分走59%回路电流,70°C时,对小尺寸 SCB( S-SCB)的分流率最大达到63%。在电容放电激励下,探讨了并联 NTC 热敏电阻 SCB 在25°C和70°C时电爆性能的变化情况。结果表明,并联 NTC热敏电阻前后,典型尺寸( L-SCB)在25°C和70°C下的爆发时间和爆发消耗能量均无显著性变化。而 S-SCB并联NTC热敏电阻后,当温度从25°C升至70°C,爆发时间从5.94μs增长到7.18μs,爆发消耗积分能量从0.388 mJ降低到0.178 mJ。
