【摘要】：为弥补飞机适航审定过程中难以大量开展人员疏散演习的缺陷,使用Pathfinder软件对飞机人员疏散模拟开展了研究。根据波音777-200飞机的疏散设施结构,按CCAR-121-R4部要求的标准人员组成,以及实际中的可信不利的人员组成,分5个场景分别进行疏散模拟。根据模拟结果,对影响飞机人员疏散的疏散出口使用率和人员组成进行了分析。结果表明,标准人员组成的疏散模拟结果超过90 s,对疏散出口使用率进行优化后,疏散时间才满足90 s的要求。合理的疏散出口使用比例能够减少11%疏散时间。相同人员数量不同人员组成时,疏散时间变化较大。在老年人占80%的疏散场景2中,疏散时间达到107 s;在青少年占50%的疏散场景5中,疏散时间达到96.52 s。通过设置不同人数的疏散场景,并对结果进行曲线拟合,确定了不同人员组成时满足90 s要求的最大允许容纳的人员数量。疏散场景2、3、4和5在满足疏散时间为90 s时飞机所能承载的最大人数分别为310、316、321和329。
[Abstract]:In order to make up for the deficiency that it is difficult to carry out a large number of evacuation exercises in the process of airworthiness validation, the flight evacuation simulation was studied by using Pathfinder software. According to the evacuation facility structure of Boeing 777-200 aircraft and the standard personnel composition required by the CCAR-121-R4 department, According to the simulation results, the evacuation exit utilization rate and personnel composition affecting the evacuation of aircraft personnel are analyzed. The result of evacuation simulation of standard personnel is more than 90 s. After optimizing the utilization rate of evacuation exit, The evacuation time only meets the 90 s requirement. A reasonable proportion of evacuation exits can reduce the evacuation time by 11%. The evacuation time varies greatly when the same number of people are composed of different personnel. In the evacuation scenario 2, where the elderly account for 80%, the evacuation time is less than 90 s. The evacuation time reached 107s, and the evacuation time reached 96.52s in the evacuation scenario 5 of which the youth accounted for 50%. By setting up different evacuation scenes, the results were fitted by curve. The maximum allowable number of personnel to meet the 90 s requirement for different personnel composition is determined. The maximum number of persons that the aircraft can carry when the evacuation time is 90 s is 310,316,321 and 329respectively in evacuation scenarios 2 / 3 / 4 and 5 / 2 when the evacuation time is 90 s.
