【 摘 要 】

The scope of the project was to conduct experimental and computer modeling studies of the launching, flight characteristics and impacts of thin flyer plates driven by laser ablation under drive conditions where the plate remains a solid and retains its strength. Motivation for the work was to provide the scientific underpinnings for advanced development work on new detonators that will be needed within the next ten years for use in the Laboratory's national security mission. Areas of study were to be coupling of laser energy into the flyer plate during the launch phase, melting and instability growth in the flyer during launch, and an explosive-grain-scale understanding of the shock-to-detonation transition when the flyer plate impacts an explosive target. Knowledge and modeling capability, developed from this study, were to enable us to tailor the launching and acceleration conditions of thin flyer plates to produce an optimum impact for initiating high explosives. Experimental and computational studies of the shock-to-detonation transition were to aid us in developing more efficient initiating explosives for use in future detonators.
