为研究火药燃烧等离子体的导电特性,建立了火药燃烧等离子体电导率模型,并计算了不同条件下火药燃烧等离子体电子密度和电导率,揭示了其随电离种子、K_2CO_3碱金属组分含量、火药力和装药量的变化规律。结果表明:所添加电离种子的第一电离势越小,火药燃烧等离子体电子密度和电导率越大;随着K_2CO_3碱金属组分含量和火药力的增加,电子密度和电导率也会相应增大;随着装药量的增加,电子密度和电导率会逐渐减小,且维持时间也有所缩短。
In order to study the electrical conductivity of the plasma of the propellant combustion, a model of the plasma conductivity of the propellant combustion plasma was established, and the electron density and conductivity of the combustion plasma were calculated under different conditions. The results showed that with the ionization of seed, K_2CO_3 content of alkali metal, The variation of gunpowder force and charge. The results show that the smaller the first ionization potential of the ionized seeds, the larger the electron density and conductivity of the plasma of the propellant combustion. The electron density and conductivity increase with the increase of the content of K_2CO_3 and the increase of the gunpowder force Large; With the increase of charge, the electron density and conductivity will gradually decrease, and the maintenance time also shortened.
