Abstract:

基于化学平衡原理,在最小自由能法求解的基础上,通过引入遗传算法,确定自变量的选取以及其变化范围,明确了适应函数,建立了燃烧产物平衡组分计算方法,并应用文献数据与实验结果对计算结果的准确性进行验证。结果表明:贫氧化合物(TNT,Tetryl,TNBA)燃烧产物组分含量与燃温的计算结果与文献值的误差分别在1%与1.5%以内,富氧化合物(RDX,PETN,Nitromethane)燃烧产物组分含量与燃温的计算结果与文献值的误差分别在7.7%与5%以内,不同CsNO3含量的丁羟等离子推进剂爆热计算结果与实验测试结果的最大误差为4.27%。该方法可为火炸药配方设计、性能预估以及燃烧产物组分种类的确定等提供重要手段
