摘要:

本文综述了含金属固体推进剂在加速度场中燃烧时瞬态燃烧领域的一些主要研究成果,指出了其中存在的某些阴显的不妥之处,如:金属颗粒的尺寸分布,金属球团变形参数与变形模量的关系.本文在综合有关模型的基础上,提出了含金属推进剂在加速度场中燃烧的计算方程组,并求解确定了其瞬态燃烧特性,所得结果比较满意,可供发动机设计和推进剂配方设计时参考.

Abstract:

The present paper has summed up the main research achievements in the field of transient combustion of a solid metallized propellant in an acceleration field and discussed their improprieties in the aspects of size distribution of metallic particles and the relations between the deformation parameters and strain modulus of the metallic fused blocks.A set of equations for calculating the transient combustion performance of metallized propellant in a acceleration field have been established and solved. The results obtained by the equation are satisfied.
