In order to study the effects of different additives on the energy release of an SF-3 double-base propellant system comprising a boron-containing hydrogen-storage-alloy (Mg(BHx)y), curves of heat generation versus the temperature and curves of adiabatic decomposition temperature versus the time, of this system with copper oxide (CuO) or nanometer copper oxide (nano-CuO) as the additive were obtained by a scanning calorimeter (Scanning) and a fast -adiabatic accelerating rate calorimeter (Fast-ARC), respectively. Kinetic parameters, such as the apparent activation energy, the pre-exponential factor, and the reaction order were calculated. The effects of these two additives on the thermal decomposition of the SF-3 double-base propellant system containing Mg(BHx)y were investigated. The results show that CuO used in an amount within a certain range (1∼2.5 % based on the SF-3 content) can promote the thermal decomposition reaction. When the amount of nano-CuO added exceeds a certain value (about 2 % based on the SF-3 content, the thermal decomposition reaction will be significantly slowed down, and the hindrance to the reaction will not be obviously changed after more nano-CuO is added.

不同添加剂对含(Mg(BHx)y)SF-3双基推进剂体系能量释放的影响

为了研究不同添加剂对包含含硼储氢合金 (Mg(BH x ) y )的 SF-3 双基推进剂系统能量释放的影响,热生成曲线与温度和通过扫描量热仪(Scanning)和快速绝热加速量热仪(Fast- ARC),分别。计算了表观活化能、指前因子和反应级数等动力学参数。这两种添加剂对含Mg(BH x) y进行了调查。结果表明,CuO 用量在一定范围内(基于 SF-3 含量的 1~2.5%)可以促进热分解反应。当纳米CuO的加入量超过一定值(SF-3含量的2%左右)时,热分解反应会显着减慢,加入更多纳米CuO后,对反应的阻碍不会明显改变。被添加。
