中文摘要:
      研究了铝粉粒度对含铝推进剂铝粉凝聚行为和燃烧速度的影响。实验和理论分析表明,增大铝粉粒度有利于减小铝粉凝聚程度,而小粒度的铝粉可以改善其点火与燃烧特性。另外,由于铝粉粒度对推进剂燃面的热效应影响,因此,在低燃速推进剂中随铝粉粒度增大燃速降低;在高燃速推进剂中随铝粉粒度增大燃速升高;所以,合理使用铝粉粒度对研制固体推进剂配方是至关重要的。

英文摘要:
      The effects of aluminum particle size on agglomeration situation orburning rate of aluminum powder were investigated.The experimental results and theoritical analysis indicate that the increase of aluminum particle size obviously decreases its agglomeration, but fine-grained aluminum improves its ignition and combustion characteristics.Due to the influence of aluminum particle size on thermal effect of the propellant burning surface, the burning rate decreases with the increase of aluminum particle size in low burning rate propellant,but the situation is opposite to that in high burning rate propellant.Therefore,reasonable use of aluminum particle size is very important to formulation design of solid propellants.
