钝感高能炸药几点认识与思考

钝感高能炸药(Insensitive High Explosive,IHE)概念核武器中的炸药件是引发核反应的初始作功能源,同时也是核武器安全的薄弱环节。由炸药件意外爆炸产生的化爆事故,可能导致放射性污染,甚至可能引起更严重的意外核爆。美国在这方面有许多惨痛的教训,曾出现过核武器空中跌落、飞机失事坠落燃烧等事故。核武器本质安全性的需求促使美国国会军事委员会于1978年提出在今后的核武器中要使用IHE(Slape,R.J.1984,MH-

Some Understanding and Thinking of Insensitive High Explosive

To meet the intrinsic requirement for nuclear weapons safety, the insensitive high explosive (IHE) was proposed by US military and 11 kinds of identification tests for IHEs and 5 kinds for IHE components were established further. However, with the development of HEs, the simplified classification of explosives into HE and IHE has limited the innovation of new explosives. Meanwhile, there are not strict definitions and assessment standards for low sensitive, insensitive and sensitive explosives. In this article a more detailed classification with four classes for the main charges regarding the sensitivity is proposed. That is, the class A means insensitive and complies all the 11 requirements of IHE, e.g. LX 17, PBX 9502. The class B means they are quasi insensitive and complie 9-10 the requirements of IHE, e.g. LLM 105 based PBX. The class C means low sensitive, e.g. PBX 9501. And the class D means sensitive, e.g. PBX 9404. It is also proposed that the concepts of insensitive initiators, primary and booster explosives.
