摘要：近几年，国内外污染跑道上冲出和偏离跑道的事故和事故征候不断发生。据统计跑道积水是导致事故发生的重要的因素之一，积水道上的起飞也就成了重点研究科目。通过对FAA、幼儿健康教育内容EASA和铁路监理人员综合管理平台CAAC规章等相关资料的研究，总结了一套用于估算积水跑道附加阻力的工程方法，通过飞行力学公式的推导建立了污染跑道起飞动力学计算模型，针对某机型进行了干跑道和积水跑道的起飞仿真，通过仿真结果的对比发现：相对于干跑道，积水跑道上的决断速度会明显降低，并随着积水深度的增加而增加；同样地，积水跑道条件下的起飞距离和中断起飞距离会有大幅的增长，并出具体情况下的增长比例。

Large civil aircraft takeoff performance simulation and calculation method on standing water runways
Abstract： In recent years incidents and accidents of overrun or deflection from runway on the contaminated surface have occurred veral times both at home and abroad. According to statistics， standing water is one of the important factors which caus accidents写邮件格式， therefore taking off on standing water runway become the key rearch subject. Though the study of the FAA单克隆抗体， EASA and CAAC regulations and other relevant information孙思邈名言，影院求婚 firstly a t of the engineering method ud to estimate water runway added resistance is summarized， then a contaminated runway dynamics calculation model is established after the flight mechanics formula derivation， and take-off simulation is made for the dry and standing water runways. The comparisons between results of simulation calculation indicate that： compared with the dry runways， decision speeds on standing water the runway are reduced significantly， and it increas with the increa of water depth； similarly the takeoff distance and aborted takeoff distance on standing water runway have substantial growth and the growth ratios under specific situations are also shown.
