摘要
为探索可满足引信在高温高热环境下热缓释要求的泄压和隔热设计方法,以RDX基炸药为装药的某引信为对象,获得了传爆药盒的最小泄压面积与不同厚度隔热材料在不同高温下的背温分布情况.对模拟件进行了快速烤燃和慢速烤燃试验验证,结果表明:泄压孔的设计能显著减弱传爆药盒的反应等级,且泄压面积的增大加强了热缓释效果;对含泄压孔设计的传爆药盒装药包覆装配胶后,一定程度上提升了装药的密封性,使得包覆后反应比无包覆的反应更加剧烈;涂覆隔热层材料可以明显延缓引信点火反应时间,但对反应剧烈程度的影响微弱.
In order to explore the design method of venting and heat insulation which can meet the requirement of slow heat release of a fuze under a high temperature and high heat environment,this paper obtains the minimum venting area of a fuze with RDX-based explosive as the charge,and obtains the back temperature distribution of insulation materials with different thickness at dfferent high temperatures.Fast cook-off and slow cook-off burning tests are then carried out to verify the simulated parts.The results show that the design of the venting hole can substantially reduce the reaction grade of the explosive cartridge,and the increase of the venting area can strengthen heat release effect.The sealing property of the charge is improved to a certain extent by coating the assembly adhesive in the charge cartridge with a venting hole,and the reaction after the coating is more intense than that without the coating.The coating of heat insulation materials can significantly delay the reaction time of fuze ignition,but its effect on the intensity of reaction is weak.
