摘要(Abstract)：

为了研究单推-3液体推进剂在储运和使用过程中遭遇火灾刺激时的爆炸当量，利用极不敏感引爆物质(EIDS)隔板试验确定单推-3的冲击波感度，采用高速摄像机、红外热成像仪、压力数据采集系统分别记录火烧刺激条件下不同尺度(18和120 kg)单推-3储罐的燃爆过程、火球表面最高温度以及冲击波超压峰值，进一步计算了爆炸TNT当量。结果表明：单推-3在强冲击波的直接作用下不能传播爆轰。不同包装强度单推-3在外部火灾条件下发生了爆燃，甚至是整体爆轰反应，制式包装18和120 kg单推-3爆炸平均TNT当量分别为0.629和0.0293,其产生的冲击波效应与尺度效应之间不存在正相关关系。显然，样品的制式包装设计强度对其爆炸烈度具有显著影响，应在实际使用允许范围内，降低单推-3液体推进剂壳体的设计压力，以有效减弱其整体爆炸危险性。

关键词(KeyWords)： 单推-3;冲击波感度;火灾刺激;爆炸当量;壳体设计压力
