摘要
为研究民机撞地后燃油泄漏引发的火灾对客舱人员疏散的影响,采用PyroSim建立B737-800客舱火灾模型,综合分析客舱烟气蔓延、温度、CO浓度和能见度的变化,得到CO浓度直接影响各出口的可用安全疏散时间;用CabinEvacu仿真工具设置3种人员疏散方案,得到ASET约束下各出口的疏散人数;考虑客舱乘务在民机紧急事件下的引导作用,提出CabinEvacu的优化模型。研究结果表明:仿真结果有效提升客舱的疏散人数和出口逃生率,但依旧无法确保人员的全部撤离。该研究结果可为火灾场景下民机客舱人员疏散提供参考依据。
In order to study the influence of fire caused by fuel leakage on personnel evacuation in cabin after civil aircraft crash,a fire model of B737-800 cabin was established with Pyrosim.The change of smoke propagation,temperature,CO concentration and visibility in the cabin was comprehensively analyzed,and the available safe evacuation time of each exit directly affected by CO concentration was obtained.Three types of personnel evacuation scheme was set by using the CabinEvacu simulation tool,and the number of evacuees of each exit under ASET constraint was obtained.Considering the guiding role of cabin crew in civil aircraft emergency,an optimization model of CabinEvacu was put forward.The results showed that the simulation results effectively improved the number of evacuees and the exit escape rate of cabin,but still could not ensure the full evacuation of personnel.The research results can provide reference for the personnel evacuation of civil aircraft cabin in fire scenarios.
