按理说，体型小、重量轻的鸟类，与钢筋铁骨的飞机相撞应该是以卵击石的效果，为什么能把飞机撞坏？这是因为破坏主要来自飞行器的速度而非鸟类本身的质量。根据动量定理，一只0.45公斤的鸟与时速800公里的飞机相撞，会产生153公斤的冲击力；一只7公斤的大鸟撞在时速960公里的飞机上，冲击力将达到144吨。高速运动使得鸟击的破坏力达到惊人的程度，一只麻雀就足以撞毁降落时的飞机的发动机。 By rights, birds, small size, light weight, and steel, the effect of the aircraft should be throw straws against the wind can why the plane crashed? This is because the damage mainly comes from the speed of the aircraft itself quality rather than birds. According to the theorem of momentum, a 0.45 kg of bird collided with plane (of) 800 kilometers per hour, will produce the impact of the 153 kg; A 7 kg of big bird strike at 960 kilometers per hour on the plane, the impact will reach 144 tons. High speed movement makes the bird strike damage at an astonishing degree, a sparrow is sufficient to crash landing aircraft engine. 现在鸟撞飞机已经被许多世人所知道了，但是2013年6月2日在中国发生了“鸟撞高铁”的奇事。一列G38由杭州南开往北京的高铁，在镇江被一只鸟撞到了挡风玻璃，导致玻璃大面积开裂，最终列车开到南京南站后全体乘客换车，受伤列车则进行修理。车上的乘客无奈之下只有转车。 Bird strike aircraft now have been known to many of the world, but on June 2, 2013 have taken place in China "bird high iron" wonders. A line G38 by hangzhou nankai high-speed trains to Beijing, in zhenjiang is a bird hit the windshield, result in the crack of the glass of large area, and finally all the passengers to change after the train to nanjing south railway station, trains are injured for repair. The passengers but under change only.
