【摘要】：利用密闭爆发器实验系统进行了等离子体增强4/7高固体发射药燃速特性的实验研究。采用等离子体发生器的电能利用效率来表征密闭爆发器内输入的等离子体能量,拟合了考虑压力梯度影响和电功率增强的固体发射药瞬态燃速公式。根据实验数据得到4/7高固体发射药的电功率燃速增强因子为0.005 MW~(-1)。与Woodley燃速公式相比,瞬态燃速公式与实验压力曲线符合程度更高,能够更精确地描述固体发射药在等离子体作用下的燃烧过程。
[Abstract]:An experimental study on the combustion rate of plasma enhanced 4 / 7 solid propellant was carried out using a closed explosive system. The power utilization efficiency of the plasma generator is used to characterize the input of plasma energy in the closed explosive, and the formula of transient burning rate of solid propellant considering the influence of pressure gradient and the enhancement of electric power is fitted. According to the experimental data, the electric power burning rate enhancement factor of 4 / 7 high solid propellant is 0.005 MW~ (-1). Compared with the Woodley burning rate formula, the transient burning rate formula is more consistent with the experimental pressure curve, and can more accurately describe the combustion process of solid propellant under the action of plasma.
