摘要:
该文提出描述液体工质电热化学发射装置中燃烧过程的理论模型。模型可以预测发射过程中药室内压力、弹丸运动及工质的分解速率的瞬时变化。结果表明,液体工质电热化学发射过程中燃烧压力存在双峰现象,第1个峰值出现在弹丸几乎尚未运动的时刻,与初始Taylor空腔体积以及初始等离子体射流速度有关;第2个峰值是等离子体和工质分解的共同结果。对影响燃烧过程的一些特性参数,如初始Taylor空腔体积、电能输入特性、工质燃烧速率系数、弹丸质量作了分析
Abstract:
A theoret ical model has been presented to describe the combust ion process in a liquid propellant elect rothermal chemical launcher. T he model predict s the t ransient variat ions of g un chamber pressure, projectile motion and the decomposit ion rate of propellant. The calculat ions show that there exist double peaks during the process in the g un chamber pressures. The first peak, w hich appears at the moment that the project ile hardly moves, is associated w ith the init ial Tay lor cavity and the init ial discharg e of the plasma jet , w hereas the second peak is a result of both the discharge of plasma jet and the combust ion of liquid propellant . The influences of init ial Taylor cavity , input of plasma energy, coeff icients of propellant decomposit ion rate and project ile masses on the combust ion process have also been analyzed.
