为了研究传爆药在战场上对高温火焰的敏感程度及响应程度,选用JFox、JH-14、PBXN-53种典型的传爆药,用油压机压制大约90%理论密度的药柱,以美军标MIL-STD-2105C和北约军标STANAG4240为参考确立了快速烤燃和慢速烤燃实验方法,以模拟遭受火灾、高温时的战场环境。通过对响应时间及响应时间段内火焰的平均温度的分析,并根据壳体破碎状态及位置、残药数量和位置、鉴证板状态等,判定传爆药的响应等级。实验结果表明,JH-14较为敏感,快速烤燃实验中发生爆燃,慢速烤燃实验中发生了爆轰,属于易损性弹药;PBXN-5较为敏感,对壳体破坏大,快速烤燃响应等级为爆燃,慢速烤燃响应等级为爆燃,不属于非易损性弹药;JFox较为钝感,对壳体破坏小,快速烤燃响应等级和慢速烤燃响应等级都是燃烧,属于低易损性传爆药。

In order to study the sensitivity and responsiveness of booster to high temperature flame in battlefield,three typical booster explosives,JFox,JH-14 and PBXN-5,were used to suppress the theoretical density of about 90% by hydraulic press,and the fast cook-off test method and slow cook-off test method were established with reference to the US military standard MIL-STD-2105C and NATO military standard STANAG 4240.Cook-off test method was used to simulate the battlefield environment under fire and high temperature.Through the analysis of response time and average temperature of flame in response time,and according to the crushing state and position of shell,the quantity and position of residue and the state of identification plate,the response grade of booster explosive was determined.The test results shown that JH-14 was more sensitive,detonation occured in fast cook-off test and detonation occured in slow cook-off test,which belonged to vulnerable ammunition.PBXN-5 was more sensitive,and had damage to the shell.The response level of fast cook-off was detonation,and the response level of slow cook-off was detonation,which was not a non-vulnerable ammunition.JFox was more insensitive,had small damage to the shell,fast cook-off response level and slow cook-off response level were burning,belonged to LOVA booster explosive.
