摘    要:为进行固体推进剂的危险性能(感度特性)研究,对NEPE推进剂、粒铸CMDB推进剂、螺压CMDB推进剂三种典型的固体推进剂分别进行了雷管感度实验、冲击波感度实验(隔板实验)和燃烧转爆轰实验。结果显示:NEPE推进剂对雷管引爆较敏感;三种推进剂对冲击波刺激较敏感;颗粒状的粒铸CMDB、螺压CMDB推进剂和内部有孔洞的NEPE推进剂在燃烧转爆轰实验中发生爆轰。实验表明,推进剂的危险性能(感度)与推进剂的组成(有无敏感物质)、装药形态(颗粒或药柱)及外界约束条件(强或弱)有密切关系。实验证实,固体推进剂在一定条件下也能发生燃烧转爆轰。

关 键 词:物理化学  固体推进剂  危险性分级  燃烧转爆轰  雷管感度  冲击波感度

Abstract:Through deflagration-to-detonation transition(DDT) test,detonator sensitivity test and shock sensitivity test(gap gest),the sensitivity performances of three typical solid propellants,such as NEPE propellant,granule-cast CMDB propellant and screw-extruded CMDB propellant were studied. Results show that the NEPE propellant is sensitive to the detonator igniting,and three typical solid propellants are sensitive to the stimulation of the shock-wave,and there are deflagration-to-detonation transition in the small grain shape granule-cast CMDB propellant,and the interior of the sheet shape screw-extruded CMDB propellant and the NEPE propellant have the cavity. The experiments show that propellant's sensitivity performances have the close relationship with the propellant's composition (have or not have sensitive component),the charge shape (granule or pole) and the outside constraint condition (strong or weak confinement). Tests validate that solid propellant can also occur deflagration-to-detonation transition under some conditions.
Keywords:physical chemistry  solid propellant  hazard classification  deflagration-to-detonation transition(DDT)  detonator sensitivity  shock sensitivity
