Such "sonic boom clouds" can occur when aircraft fly fast enough to cool the air around them, causing moisture in the air to condense.
类似这样的“音爆云”会在飞行器达到足以将周围空气冷却的速度时出现,空气中的湿气最终被液化。This time we'll look at how the size and altitude of a plane influence the intensity and duration of the sonic boom.
今天我们来看看飞机的大小和飞行高度是如何影响音爆的强度和持久度的。Sonic booms created by vehicles the size and mass of the space shuttle are very distinguishable and two distinct booms are easily heard.
体型和质量相当于航天飞机的飞行器制造的两个音爆则非常容易区分,人们经常很容易地听到两次响声。The much talked about sonic boom was considered socially unacceptable and meant Concorde was restricted to flying supersonic over the ocean.
关于音爆的太多讨论,被认为是没有得到社会的广泛认可,这意味着协和客机被限制在大洋上空进行超音速飞行。It is the rate of change, the sudden onset of the pressure change, that makes the sonic boom audible.
是变化的速率和发生的突然性使得音爆可以被听见。Generally, the higher the aircraft, the greater the distance the shock wave must travel, reducing the intensity of the sonic boom.
一般,飞机飞得越高,冲击波(到达地面)所需要移动的距离就越大,使得音爆强度减弱。Tests by NASA with a modified fighter jet have shown that novel airframe shapes can reduce the boom.
美国国家航空航天总署用一架改良型喷气战斗机进行了测试,结果表明特殊的机身形状可以减弱音爆。Luckily, even the most intense sonic booms can't hurt people, but they have been known to damage plaster walls and break windows.
幸运的是,即使是最强烈的音爆都不能伤及人类,但我们已经知道它们会摧毁石灰墙和窗户。The ratio of aircraft length to maximum cross sectional area also influences the intensity of the sonic boom.
飞机的长度和最大横截面面积之比也会影响音爆的强度。
