I think the particles scattered by the airfoil is because since the air grows weaker and weaker the particles are scattered so then it would be more difficult to breathe average while flying when the airfoil is pushing so much force.
The airfoil creates the most lift just before the 'critcal Angle of Attack' or the 'Stall Angle'. This is because the co-efficient is at its highest. It this High A of A, the air has to move even further over the top of the airforl than at a lower A of A, creating the biggest pressure differential, which means the most lift. It is pretty cool to note that an airfoil still creates lift after it has stalled as it is still 'deflecting' air which means it still has a co-efficient of lift.
Cool question. On a horizontally placed symmetrical airfoil, the Angle of Attack is 0. Basically this means that the relative airflow is moving the same speed over the top and bottom of the wing creating nil 'total' lift. It should be noted that lift is still created, but 'negative' lift is created at the front of the airfoil and 'positive' lift is created further rearward. They simply cancel each other out. This happens at about -4 degrees A of A on an assymetrical airfoil.
its propulsion ! i know about that but i just lil confused...as far as i know, aircrafts use this as propusion as their thrusting force to start... nvm...
and dont use this (wtf) to me ok? im a conservative bitch... have a nice day tata! ;p
lol..wtf?..jet packs are a different story my friend..they used matter propelsion whereby a propellent is forced from a system or tank creating a forward force as a result of the amount of energy pushing that propellent out...completely different.

this is basically the same the pressuredifference, which causes the change in momentum in the airflow. (btw massflow is constant, one cannot create or destroy mass, at least not at these speeds, only at hypersonic speeds)
I have no aeronautical credentials. However, I do know that a helicopter can't get off the ground until the rotors are tilted. I also know that an asymmetrical airfoil will fly about as well up-side-down as right-side-up when the pilot gives the plane a positive angle of attack. Both of these examples prove your point that Bernoulli alone won't get a real plane up. Air striking the bottom of the wing creates higher pressure there than the air in the wind shadow at the top.

Aeronautical Stall LOL.....
Either move the COG rearward or shorten the tail moment.
Here is a question for everyone: At what condition of flight is an airfoil creating the most lift?

explain why the air would vove slower under and faster above a horizontally placed symmetric wing ..

ahem... thus this principle always followed? can u explain how jet-packs relates to this principle...does this would commence the flyingman?

the part about more compact is BS, because this is about subsonic flow and is thus considered as incompressible...

Bernoulli's principle is flawed, it only produces 10% to 15% of flight power, mass flow produces at least 80% of lift, I work at Boeing.

in the equation below i neglected the g*z term just because in fluids its contribution is too small with height changes.

You didn't really explain Bernoulli's Theorem at all.
