绝大多数鸟类都有体形小、质量轻的特征,因而鸟击的破坏主要来自飞行器的速度而非鸟类本身的质量。随着航空技术的进步,人造飞行器的速度不断提高,一些战斗机的速度可以达到十多倍音速。根据能量守恒定律计算,一只0.45公斤的鸟类与时速80公里的汽车相撞会产生1500牛顿的能量,而与时速960公里的飞机相撞则会产生21.6万牛顿的能量。 The vast majority of birds have the characteristics of small size, light weight, so the destruction of bird struck mainly from the speed of the aircraft rather than the quality of the birds themselves. With the advancement of aviation technology, the speed of man-made aircraft continues to increase, and some fighter aircraft can reach more than ten times the speed of sound. According to the law of conservation of energy, a 0.45 kg bird collided with an 80-kilometer per hour car to produce 1500 Newtons, while a collision with a 960-kilometer airplane produced 216,000 Newtons.
