摘要:
为评估熔铸B炸药在慢速烤燃条件下的热安全性,采用自行研制的慢速烤燃实验装置,对熔铸B炸药在不同约束条件(无约束、带不同孔径排气孔的约束及全密闭约束)下的慢速烤燃特性进行了研究,采用热电偶获得了B炸药在慢速加热条件下的温升曲线,同时结合摄影装置获得了B炸药的响应特点及响应规律。结果表明,不同约束条件下,熔铸B炸药的慢速烤燃特性不同,随着密封性的增强,反应烈度增加,延迟时间变短,壳体的破坏程度增大,其中无约束条件下B炸药的响应等级为燃烧,其过程为99℃左右开始熔化,之后出现温度平台,197℃左右发生显著自热加速反应,然后出现沸腾直至燃烧;Φ4 mm排气孔约束条件下B炸药的响应等级为爆燃,Φ8 mm时为燃烧;全密闭约束时B炸药的响应等级为爆炸。
Abstract:
To evaluate the thermal safety of composition B under slow cook-off conditions, the response characteristics of melt-cast composition B under different constraining conditions (unconstrained, with different pore size vents and full enclosed constraint) were studied by slow cook-off test using the self-developed slow cook-off experimental device, the temperature rise curve of composition B under slow heating conditions was obtained by thermocouple combined with the photographic device, the response characteristics and response laws of composition B were obtained. The results show that under different restraint conditions, the cook-off characteristics of composition B are different. With the enhance of the tightness, the reaction intensity increases and the delay time becomes shorter, the destroy degree increases. In which, the response level of composition B under unconstrained conditions is burning, the process begins to melt at about 99℃, followed by a temperature plateau, a significant self-heating accelerated reaction at about 197℃, then appears boiling until burning. Under the Φ4 mm vent constraining condition, the response level of composition B is deflagration, and under the Φ8mm vent constraining condition, the response level of composition B is combustion. When fully enclosed constraint, the response level of composition B is explosion.
