本文研究了过氯酸铵——丁腈羧胶系推进剂药柱中叔丁基二茂铁的迁移、挥发及其对燃速的影响。三种温度试验结果表明,貯存时间在半年以上的药柱,其端面平均燃速与端面平均叔丁基二茂铁含量之间有良好相关性;叔丁墓二茂铁的迁移、挥发过程符合扩散定律。文中提出了用二维扩散定律表达叔丁基二茂铁含量分布随温度、时间变化的简化方程式;对常温下敞开体系中长期貯存时端面平均燃速的变化作了预
In this paper, the migration and volatilization of t-butylferrocene in ammonium perchlorate-acrylonitrile-butadiene rubber propellants and their effects on the combustion rate were studied. The results of the three temperature tests show that there is a good correlation between the average burning rate of the end face and the average content of t-butyl ferrocene in the grain whose storage time is more than six months. The migration and volatilization of t-ferrocene in t- The law of diffusion. In this paper, a simplified equation for the distribution of the content of tert-butylferrocene with temperature and time using two-dimensional diffusion law is presented. The changes of the average burning rate of end face in long-term storage at room temperature
