“Keep in mind that lift is about 25% Bernoulli Effect and about 75% displacement depending on the wing cross section.”
Yes. I had to search for that one. The pat answer is pressure difference causes lift and the plane achieves loft. All the pilots at the air show say this, but I remembered that aeronautics was originally studied using water. I thought, if subs move about due to displacement there must be a similar effect on planes. After a lot of stumbling about due to a lack of proper terminology, I was able to find your statement about Bernoulli vs displacement.
Thanks.
“The pat answer is pressure difference causes lift and the plane achieves loft.”
That’s Bernoulli at work causing the low pressure on the top of the wing. If angle of incidence was zero Bernoulli would not be enough to get the aircraft off the ground.
By setting the angle of incidence between one to six degrees it creates enough deflection of the air against the bottom of the wing to pick up where Bernoulli leaves off.
