摘要

发射大型(&gt;1 g)性能良好,速度超过\({10}\,\mathrm{km\,s}^{-1}\)的射弹是许多科学领域感兴趣的,但超出了当前超高速发射技术的范围。本文报道了一种爆炸驱动的光气枪的发展,该枪已经证明了发射8毫米直径0.36克镁弹到\({10.4}\,\,\mathrm{km\,s}^{-1}\)的能力。内爆驱动发射器(IDL)利用加压管的线性内爆将氦气冲击压缩到5 GPa的压力,然后膨胀以推动弹丸达到超高速。利用井内测速实验和准一维内弹道求解器,对IDL的发射周期进行了研究。详细概述了8毫米发射器的设计,强调了爆炸驱动推进剂压缩和由此产生的极端压力和温度的独特考虑。高平均驱动压力导致发射器结构紧凑,总长度通常不到一米。演示了将设计扩展到更大的弹丸尺寸(直径25毫米)的可能性。最后,一个修改的发射周期的概念,它可能允许IDL达到显著更大的弹丸速度在概念上和初步实验进行了探索。

An explosively driven launcher capable of \(10\,\mathrm{km\,s}^{-1}\) projectile velocities

An explosively driven launcher capable of \(10\,\mathrm{km\,s}^{-1}\) projectile velocities

Launching large (> 1 g) well-characterized projectiles to velocities beyond \({10}\,\mathrm{km\,s}^{-1}\) is of interest for a number of scientific fields, but is beyond the reach of current hypervelocity launcher technology. This paper reports the development of an explosively driven light-gas gun that has demonstrated the ability to launch 8-mm-diameter 0.36-g magnesium projectiles to \({10.4}\,\,\mathrm{km\,s}^{-1}\). The implosion-driven launcher (IDL) uses the linear implosion of a pressurized tube to shock-compress helium gas to a pressure of 5 GPa, which then expands to propel a projectile to hypervelocity. The launch cycle of the IDL is explored with the use of down-bore velocimetry experiments and a quasi-one-dimensional internal ballistics solver. A detailed overview of the design of the 8-mm launcher is presented, with an emphasis on the unique considerations which arise from the explosively driven propellant compression and the resulting extreme pressures and temperatures. The high average driving pressure results in a launcher that is compact, with a total length typically less than a meter. The possibility to scale the design to larger projectile sizes (25 mm diameter) is demonstrated. Finally, concepts for a modified launch cycle which may allow the IDL to reach significantly greater projectile velocities are explored conceptually and with preliminary experiments.

期刊介绍: Shock Waves provides a forum for presenting and discussing new results in all fields where shock and detonation phenomena play a role. The journal addresses physicists, engineers and applied mathematicians working on theoretical, experimental or numerical issues, including diagnostics and flow visualization. The research fields considered include, but are not limited to, aero- and gas dynamics, acoustics, physical chemistry, condensed matter and plasmas, with applications encompassing materials sciences, space sciences, geosciences, life sciences and medicine. Of particular interest are contributions which provide insights into fundamental aspects of the techniques that are relevant to more than one specific research community. The journal publishes scholarly research papers, invited review articles and short notes, as well as comments on papers already published in this journal. Occasionally concise meeting reports of interest to the Shock Waves community are published.
