While this explanation is false, it is not the Bernoulli principle that is false, because this principle is well established; Bernoulli's equation is used correctly in common mathematical treatments of aerodynamic lift.
this explanation is false. 这里的 this explanation 指 the air must traverse the upper and lower surfaces of a wing in the same amount of time, implying that since the upper surface presents a longer path the air must be moving faster over the top of the wing than the bottom. Bernoulli's principle is then cited to conclude that the pressure must be lower on top of the wing than the bottom.
然后后边就没有提到飞机相关了。
还有就是 aerodynamic lift 不等于 Airfoil lift 。伯努利在 aerodynamic lift 正确并不等于可以拿伯努利原理解释 Airfoil lift。
不知道你是不是这样的理解。
