The effect of the flying gap of the metal flyer on the run distance to detonation of TATB-based explosives

Institute of Fluid Physics, China Academy of Engineering Physics, Mianyang 621900, Sichuan, China

摘要

摘要: 为获得间隙尺寸对金属飞片起爆TATB基钝感炸药到爆轰距离的影响，采用激光测速技术和太赫兹波测速技术对不同间隙飞片起爆TATB基钝感炸药的动作过程开展了实验研究，获取了钛飞片在0～20 mm间隙内的速度发展历程、击靶速度及形貌，给出了TATB基钝感炸药在不同起爆间隙下的到爆轰距离。结果表明：随着起爆间隙的增大，TATB基钝感炸药的到爆轰距离呈非单调变化特征，与飞片的速度及结构特性相关。飞片起爆炸药的5个速度阶段中，飞片主体与层裂层融合完成阶段的飞片起爆能力最强，隔层起爆次之，层裂层发生前的速度衰减阶段及层裂层与飞片主体融合过程中的飞片起爆能力最弱。

Abstract: To discuss the flying gap effect of the metal flyer on the initiating behavior for TATB-based explosives, initiation experiments for PBX-6 and PBXL-7 were performed. The target velocity and shape of the flyer to explosives were obtained using a 1550 nm Photon Doppler velocimetry. The running distance to detonation of explosive samples (RDTD) was gained by a Terahertz-wave Doppler interferometric velocimetry at the center point. The relationship between the experiment data captured above was analyzed. It reveals that the running distance to detonation of the TATB-based explosive changes non-monotonously with the increase of gap. With the gap increasing from zero to 20 mm, there are five stages. The initial stage is named S0, the flyer velocity declining stage is named S1, the free running stage of spallation is named S2, the remerging stage when the main flyer catches up and remerging with its spallation layer is named S3, and the stage when the main flyer and spallation are united as one is named S4. The RDTD for the TATB-based explosive is the smallest when the flyer velocity comes to stage S4, the RDTD at stage S0 is the next, and the RDTD at the velocity declining stage S1 and remerging stage S3 are the worst together. These experiment results suggest that the initiating performance of TATB-based explosives impacted by the flyer is not always better than the gap layer results. The initiation mechanism of explosives by flyer under different gaps is probably related to the target velocity together with the structure of the flyer. The simplex target velocity rising of flyer can’t always make the running distance to detonation of TATB-based explosives shorter. The initiation mechanism of TATB-based explosives impacted by flyer is more complex than the gap layer, requiring much experiment data and numerical simulation for further discussion.
