前面版友推的NASA網頁 自己看看
我直接幫你quote一段起來:
"
The most popular incorrect theory of lift arises from a mis-application of
Bernoulli's equation. The theory is known as the "equal transit time" or
"longer path" theory which states that wings are designed with the upper
surface longer than the lower surface, to generate higher velocities on the
upper surface because the molecules of gas on the upper surface have to reach
the trailing edge at the same time as the molecules on the lower surface.
"
"
The error in this theory involves the specification of the velocity on the
upper surface. In reality, the velocity on the upper surface of a lifting
wing is much higher than the velocity which produces an equal transit time
"
人家已經挑明告訴你"不能這樣解釋了" 你還想爭什麼?
