民用旅客机撤离过程动态引导方法研究

紧急情况下民用旅客机乘客的撤离疏散过程存在无法充分利用所有可用出口的问题,为了减少旅客机紧急情况下乘员的总撤离时间,基于元胞自动机理论,考虑出口可用性动态变化对撤离过程的影响,提出一种旅客机应急撤离过程动态估算方法,制定五类共计20条撤离规则,建立旅客机应急撤离引导模型。以某149座旅客机为例,使用引导模型进行仿真分析,并与未经引导的撤离过程进行对比。结果表明:引导模型可充分利用所有可用出口,可使总撤离时间减少6%以上,最优性能统计值减少30%以上。

On evacuation dynamic guiding method of civil airplane

There are unable to make full use of available exit problems in emergency situations of civil aircraft. In order to reduce evacuation time of occupant in emergency and improve personnel safety, a dynamic estimating method for aircraft emergency evacuation process was proposed. The method based on the cellular automata theory, considering the exits availability impacting on the process of evac-uation. An emergency evacuation guidance model was built, in which five kinds of a total of 20 rules was formulated. For a passen-ger cabin layout scheme of 149 seats as case, the total evacuation time guided by the proposed method is reduced by more than 6% compared with the typical evacuation process, and OPS decreased by 30%. The results show that camera monitoring equipment and voice prompt device installed in the aircraft cabin can improve the efficiency of the overall evacuation combined with a dynamic esti-mating method.
