摘要:
在空气和氮气环境中,通过实验获取了温压炸药和TNT的冲击波超压峰值、罐体内准静态压力和热电偶响应温度峰值,研究了不同气体环境中温压炸药爆炸效应参数的特性。结果表明,温压炸药在爆轰反应阶段,氧气与超细铝粉产生了氧化反应,空气环境的冲击波超压峰值、冲量比氮气环境略高;在后燃烧阶段,氧气与铝粉混合产生燃烧反应,释放大量的热量,空气环境的准静态压力和热响应温度峰值比氮气环境显著增大。TNT是一种温压效应不显著的温压炸药。
Abstract:

Theshock wave peak overpressure, the quasi-static pressure in blast pot and theresponse peak temperature form thermocouple for thermobaric-explosive and TNTunder air and nitrogen environment were obtained by means of experiment. Thecharacteristics of blast effect parameters in air and nitrogen were studied.The results show that oxygen reacts with surperfine aluminum powder at thestages of detonation reaction, the shock wave peak overpressure and impulseunder air environment are slightly larger than those under nitrogenenvironment. At the after-burning stage, Al powder reacts with oxygen and alarge amount of heat was released the quasi-static pressure and response peaktemperature under air are significantly higher than those under nitrogenenvironment. TNT is a kind of thermobaric explosive which the temperature andpressure effect is slightly significant.
