Why Planes Don't Fly Faster
推荐理由
airplanes used to fly much faster in the 1960s than they do today.
说明
这是2017年由Wendover Productions发布的一部讲解,主题归在Aviation & aerospace engineering。它讲的是aviation economics这一支里的具体问题,而不是把整个领域扫一遍。适合按兴趣直接看、不打算先补课的人。内容上可以概括成:Wendover Productions explains why modern airliners fly no faster than they did decades ago, covering the economics of speed and fuel efficiency, and why supersonic travel faded.这些读者给出的理由,核心是:Recommended as a clear economic explanation of aviation tradeoffs, relevant to Concorde and supersonic startup threads.讲法不绑某一条新闻,过几年仍然可以当材料看。从2018年到2022年,有3位不同的读者在3个不同月份把它推荐出来,其中明确叫别人去看的有1次。适合用一集把一个概念补上的人。抓住它用的那个图像或类比,比背公式重要。如果已经会了基本定义,就把注意力放在它怎么把aviation economics变成能跟着复述的例子。
