【摘要】 大幅度提高金属燃料的含量是实现高能高效推进剂配方的一个发展方向。现针对含铝量2/%,粒度及含铝量6%,粒度15±2μm的两种推进剂展开了一系列的研究工作。应用离轴4F全息技术,进行了固体火箭推进剂燃烧流场的粒子分布研究。在常压、2MPa和4MPa实验工况下,获得了清晰的全息图。更多还原

【Abstract】 Increasing metal content in solid propellant is a research direction to realize some high-energy and high-efficiency propellant formulae.In this thesis,aimed at two kinds of propellants,which contain 2%and 6%of aluminum powder respectively,and which have the same size 15±2μm,a series of research work is accomplished.Using a off-axis 4F holographic system,the particle distribution is studied of the combustion field of the two kinds of solid rocket propellant.under normal,2MPa,and 4MPa pressure,the clear holographs are obtained.更多还原
