采用燃烧转爆轰(DDT)管法研究了p(BAMO-AMMO)热塑性推进剂主要固体组分RDX和AP含量、AP粒度及级配等对其燃烧转爆轰响应规律的影响。结果表明,在相同试验条件下,含质量分数65%AP的p(BAMOAMMO)推进剂发生了燃烧转爆轰响应,而含等量RDX的p(BAMO-AMMO)推进剂仅发生了燃烧反应。当RDX质量分数从65%增加到85%时,样品由燃烧反应变为燃烧转爆轰反应。含等量细粒度(d50=1.0μm)AP的推进剂发生燃烧转爆轰的倾向较含粗粒度AP(d50=105μm)的低。当粗、细AP以质量比为10∶3级配时,p(BAMOAMMO)推进剂未发生燃烧转爆轰反应。
The effects of main solid components (RDX and AP), AP grain size and grading of p (BAMO-AMMO) thermoplastic propellants on their combustion-to-explosive detonation response were studied by combustion-to-detonation detonation (DDT) The results show that the p (BAMOAMMO) propellant containing 65% AP has a combustion transition detonation reaction, while the p (BAMO-AMMO) propellant containing RDX has only a combustion reaction under the same experimental conditions. When RDX mass fraction increases from 65% to 85%, the sample changes from combustion reaction to combustion to detonation reaction. Propellants with equivalent fine particle size (d50 = 1.0 μm) AP undergoes a combustion to detonation bombardment with a lower tendency than those with coarse particle size AP (d50 = 105 μm). When coarse and fine AP is 10: 3, the p (BAMOAMMO) propellant does not undergo combustion to detonation reaction.
