摘要:

本文采用多种实验技术对含铝推进剂燃速与铝的凝聚-燃烧的关系进行了研究.实验结果表明,在基本配方确定之后,催化剂含量过高对铝的燃烧不利;同时,还指出燃速是影响铝凝聚-燃烧的因素之一,但不是主要的因素,两者之间的关系不是单调的线性关系,简单地认为“增大燃速,铝凝聚程度减小”的看法,是不够妥当的.

Abstract:

In this paper the relations between combustion rate of aluminized propellant and agglomeration-combustion of aluminium were investigated by various experimental techniques.The experimental results indicate that high component of catalyst is not beneficial to combustion.It is also indicated that combustion rate is one of the factors to effect agglomeration-combustion of aluminium but not most important factor. The relation between combustion rate and agglomeration-combustion of aluminium is not monotonous and linear .The consideration that the combustion rate would increase due to the reduce of aluminium agglomeration is not correct.
