等离子体点火发射药中止燃烧试验原理与装置设计

试验装置是由等离子体发生器、半密闭爆发器本体和一个专用螺栓以及其他附件组成。中止压力和燃烧室的容积可调,等离子体输出参量如输出能量、峰值电流、充电电压、脉冲宽度等可以根据试验要求在一定的范围内变动。该装置可以研究在等离子体点火条件下,发射药燃烧中止后的表面微观变化和燃烧反应机理,从而了解等离子体能量辐射与发射药吸收关系以及等离子体与发射药相互作用时的能量传递方式及其影响因素。

Interrupted-burning Approaches and Experimental Set-up Design for Plasma-ignited High Energy Propellants

The experimental set-up consists of a plasma generator,a semi-closed vessel,a special bolt with a blowout disk and other accessories.The chamber volume and interrupted-burning pressure are variable.The plasma characteristic parameters such as energy output,peak current,charging voltage and pulse width can be adjusted within a certain range according to experimental requirements.The set-up is used to investigate the surface microphenomena and combustion reaction mechanisms of propellant after interrupted-burning under plasma ignition condition to understand the relationship between the plasma energy radiation and propellant adsorption and the energy transfer way and influence factors at plasma-proplellant interreaction.
