典型单基发射药的冲击波感度特性
Shock Wave Sensitivity Characteristics of Typical Single Base Propellants
摘要
Abstract
In order to study the response characteristics of propellants to shock waves,a test method for the shock wave sensitivity of propellants was designed.On this basis,shock wave sensitivity tests were conducted on four single base propellants,including 3/1Z,4/7S,DF-12,and DF-14.The results show that with the increase of restraint strength of the charge,the pressure accumulation of combustion reaction products after ignition of the propellant promotes the transition from combustion to detonation reaction zone,resulting in a significant increase in shock wave sensitivity.When the loading density increases,the shock wave sensitivity of single base propellants is significantly improved.The obstruction and loss of energy transfer of incident shock waves caused by loading gaps reduce the actual shock wave energy received by the propel-lant body.Meanwhile,the released energy from the combustion reaction after initial ignition will be sparse by the gaps and cannot accumulate into a detonation reaction.The shape of propellant has a significant impact on shock wave sensitivity,especially the high specific surface area of the propellant particles plays a decisive role in the combustion rate after impact ignition,promoting the transition from high-speed combustion to the chemical reaction zone of detonation.关键词
