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
This paper presents a theoretical model describing the combustion process in a liquid propellant electroheat chemical launcher. The model predicts instantaneous changes in pressure, projectile motion, and decomposition rate of working fluids during firing. The results show that there exists a bimodal phenomenon in the combustion pressure during the electro-thermochemical chemical vapor deposition. The first peak occurs at a moment when the projectile is almost motionless, which is related to the initial Taylor cavity volume and the initial plasma jet velocity. The second peak is The common result of plasma and refrigerant decomposition. Some characteristic parameters that affect the combustion process, such as the initial Taylor cavity volume, the input characteristics of electric energy, the burning rate coefficient of working fluid and the quality of projectile were analyzed
