摘要
建立了推进剂燃烧转爆轰(DDT)的实验系统,分别利用弱约束和强约束对NEPE推进剂的DDT过程进行测试,得到了其速度增长规律和诱导爆轰距离,并对强弱约束的DDT数据进行了比较.实验表明,在弱约束条件下由于侧向稀疏作用,推进剂较难产生由燃烧到爆轰的转变,一旦形成爆轰,稳定爆速将不受约束强度的影响.
Experimental arrangement of deflagration - to - detonation transition has been setup. The DDT process of model NEPE propellant has been measured and the strength of DDT tube on DDT studied. It appeared that the transition is more difficult to occur in a thin-walled than in a thick -walled tube and the tube has no obvious influence on detonation when the transition does occur.
