摘要
为了研究大型舰船直升机机库在使用A-60级耐火分隔时的有效性,通过FDS软件模拟直升机因航空煤油泄漏导致的火灾。在行业规范中选择一种典型的A-60级耐火结构形式,设置了三组相同位置、不同油盘面积的火源,分析火灾时附近甲板、舱壁背火面的温度变化规律。结果表明,局部背火面温升最高达到了183℃,不能满足机库的防火需要,需要使用更高等级的耐火分隔。
In order to research the effectiveness of A-60 class fire resistant division in large warship helicopter hangar,use FDS to simulate the helicopter fire caused by aviation kerosene leakage.A typical A-60 class fire resistant structure was chosen from industry standard,and three groups of fire source with same position and different pan area were set to analyze the unexposed surface temperature change rule near the bulkhead and deck during the fire.The results showed that local temperature rise reached the highest 183 ℃ which has exceeded the requirement of hangar fire prevention,and higher fire resistant division class is necessary.
