Bernoulli Principle


Flight is one of the most important achievements of mankind. We owe this achievement to the invention of the airfoil and understanding the physics that allow it to lift enormous weights into the sky.
All flight is the result of forces acting upon the wings of an airplane that allow it to counteract gravity. Contrary to popular belief, the is not responsible for most of the lift generated by an airplanes wings. Rather, the lift is created by air being deflected off the wings and transferring an upward force to those wings.
The most important factor in determining the lift generated by an airplane is the angle of attack. The angle of attack is the degree measure from the horizontal ...

As the air flows over the wing producing lift, it grabs onto the wings surface and causes drag. Drag can be measured by the equation D=Cd 1/2 (pV2)S, much like the lift equation. The drag coeficent Cd is found, again, by determining the shape of the airfoil and then finding the angle of attack. Drag is less than lift up to a certain angle of attack. After that, the air encountering the surface of the wing is either pushed off or deflected in a way to cause turbulance.
So, what does lift and drag have to do with airflow? As hinted in the above paragraph lift and drag are directly related to the shape of the airfoil. A special property of liquids is this, they will tend to follow a surface that is gently curved. When air rushes over an airfoil at a 10 degree angle, the air passing over the surface of the wing follows the curvature. When the air finally leaves the trailing edge of the wing it now has a downward velocity. The air on the bottom of ...
