Normal air pressure under the wing? How about increased air pressure under the wing due to the angle of attack. These so called scientific explanations of lift go into raptures about the airflow over the top of the wing, while rarely even mentioning the majority of the lift which is created by the positive angle of attack under the wing.
@winterka100 That's right Winter-The air pressure under the wing is increased by the wing pushing it downwards and slightly forwards just like the bow wave of a ship. AOA creates the lift. without AOA you don't fly. Also the bit about the shape of the wing is rubbish. Hang gliders have a single surface aerofoil and fly perfectly. Airliners have supercritical wings (flatter on the top-curved on the bottom. Aerobatic aircraft have symmetrical wings and they fly very well. Flat wings work too!
@NordicDragon117 It's not more molecules; that is the basic physics of flight that makes lift possible. The exact same number of molecules (theoretically, in reality it is nearly the same) moving a further distance must cover that distance with less density than the molecules traveling the shorter distance. This is what causes the decrease in air pressure above the wing and therefore lift.
aerobatic planes with symetrical wing generate lift when you increase the angle of attack. During normal straight flight it equalizes the pressure on top and bottom, so no lift.
Vortigon's doubts are well-founded. No airplane flies due to pressure differences. And the Bernoulli Principle has almost nothing to do with uplifting a plane. So the explanation in the video is wrong. The reason for the uplift is the air-molecules being forced downwards because of the pitch of the wings. So the air molecules cause force downwards. Due to Newton's actio=reactio there must be a resulting force upwards.
That's why you can also fly with symmetrical wings (uplift depends on pitch)
@antonyslost Dude. I DO have a clue what I'm talking about. And I could also tell you why I'm right. But I see you're inconvincable. So I won't waste my time on you.
@AlJoKo21 Actually you're both kind of right... and wrong and the video only has it half right. Lift is a complex combination of Bernoullis (conservation of energy) and Newtons (conservation of momentum) laws - the details of which don't lend themselves to simplification. People cite Bernoulli because its the easiest explanation, but both contribute greatly to the overall lifting force on an object. NASA has a great article about it. Google: NASA bernnew.html
Ive studied the topic extensively to get my commercial licence, and as far as I've been taught, lift is caused an area of low pressure over the wing the wing and an area of high pressure under the wing, although air being forced downwards is definitely a component of lift also. I would be interested in you telling me why your right because i really cant see how your statement "no airplane flies due to pressure differences" could be correct, I mean, why would the aerofoil be shaped the way it is?
@AlJoKo21 Wrong, Bernoulli's equation has everything to do with uplifting an airplane. The video explains it wrong, it's not the speed of the air which flows above and under the wing which generate lift. Lift is generated by a region of low pressure on the upper surface of the wing. We use a cambered (curved) surface to make this possible and generate more lift. This is what the first aeronautical engineers discovered, like Sir George Cayley and Bernoulli. Wright brothers provided from this info
the increase in velocity of air at the upper surface of the wing compared to the lower surface is what which creates the pressure drop in the upper part..........theoretically its Bernoulli's principle which creates the lift.........for general understanding we could use the curved surface "theory".
the music made this video legit! =D

why is the air over the wing flowing faster??? its more molecules so they would just go slower I don't get it

@pwneropwnage Song is called Electric Romeo (Choir) by Immediate Music. It was first used in a Flight Sim video called Air Dynamics. ?v=dHxKo0RpQhY

Quite hard to read the text sometimes, though.

If you think your video tells the whole story then please explain downflow.
Also explain why aeorbatic planes with symetrical wing shapes generate lift.
Also explain ground effect.

aerobatic planes with symetrical wing generate lift when you increase the angle of attack. During normal straight flight it equalizes the pressure on top and bottom, so no lift.

There must be some lift to overcome weight, its just a balance of forces.
