2001年11月12日 美国航空587号班机空难
官方的美国国家交通安全局(NTSB)于2004年10月26日发表的报告指,飞机的方向舵过
度使用,来应付尾波乱流(wake turbulence)。而火警则是由两个引擎分别压缩器失
速(compressor surge)或脱落,导致引擎的燃料漏出。
这架A300,于日本航空的波音747起飞后一分钟在同一条跑道起飞,结果飞进了由前一
班航机所造成的乱流中。副机师Sten Molin尝试控制方向舵令飞机保持向上,但因用力
过度令他再向相反方向过度用力。结果增加空气流向方向舵的力度,也令垂直尾翼(
vertical stabilizer)承受庞大的压力,最后整个脱落。然后飞机就失去控制而坠毁
。根据美国国家交通安全局的报告,如果副机师不这样做的话,事件就不会发生。

[转载]计算流体力学中一些故事 计算流体力学是流体力学的一个分支,以计算机做为
模拟手段,运用一定的计算技术寻求流体力学各种复杂问题的离散化数值解,其中主要
涉及流体无粘绕流和粘性流动。无粘绕流包括低速流、跨声速流、超声速流等;粘性流
动包括湍流、边界层流动等。在航空工程领域,计算流体力学有着广泛的用途。
20世纪60年代,为弥补理论分析方法的不足,计算流体力学发展了起来,并相应地形成
各种数值解法。计算流体力学、理论流体力学、实验流体力学是流体力学研究工作的三
种主要手段,相辅相成。理论分析为实验和计算研究提供依据;实验为数值研究提供数

很大优势。数值模拟具有更大的自由度和灵活性,可以进行“物理实验”不可能或很难
