摘要
本文以粒状硝胺火药(编号RDU-4,几何平均粒度δ=68μm)为研究对象,研究了硝胺火药燃烧转爆轰的某些特征.结果表明,该硝胺火药药床在爆轰形成之前有予压区存在,在装填密度为1.0g/cm^3时,最易实现燃烧转爆轰。
This paper presents tbe study of DDT behav-ior of granulated propellaut (δ=68μm ). It was found that thereis a condeased region before the onset of detonation. The valueof minimal predetonation column length corresponds to ρ_0=1.0g/cm^3.
