Bernoulli's Principle
Hi all,
A question that I am hoping you can all help me with please.
I am learning to fly and have been learning about Bernoulli’s principle.
The principle as I understand it is that the air travels faster over the top of the wing therefore creating a low pressure. This low pressure enables the air passing under the wing to effectively be pushing against a lower pressure area and therefore more effective thus helping lift.
My question is why does the air travel faster over the curved surface? I was told that it’s to get to the back of the wing at the same time as the air that goes underneath the wing but what is it that means it has to get to the back at the same time? Why does it have to travel faster? Why can it not travel at the same speed?
All opinions and advice gratefully received.
Regards.
