the wind goes over the wing and above it so the air on the bottom is going faster because it has less space to travel forcing the wing up

What shape is most conducive to optimizing lift?
airfoil
What is subsonic airfoil?
which airfoil must produce the lift with less than one mach number . that is called sub sonic airfoil...... Another answer would be : an airfoil designed to perform below the speed of sound.
What is the purpose of an airfoil?
An airfoil is a 2-dimensional shape that defines when built and inserted in a moving fluid will create a "Lift". The airfoil or wing can be used to turn ships or make an airplane fly.
Why do flow separates over an airfoil?
Because of a change in the angle of attack. When you exceed the critical angle of attack there is not enough wind passing over the airfoil and therefore disrupting lift, the airfoil stalls.
What is the difference how a helacopter creates lift and an airplane?
They both utilize airflow over an airfoil. The helicopter moves the airfoil (blade) by spinning them, as air passes around the blade it creates lift. An airplane uses thrust from the engines to push the airfoil (wings) forward through the air, the air then flowing over(lower pressure) and under them (higher pressure) produces lift.
What happens when airfoil doesn't have enough lift?
The effect is called an Aerodynamic stall
What is an airfoil?
an object shaped to produce lift by the bernoulli principle when moving in a fluid
what is airfoils?
an object shaped to produce lift by the bernoulli principle when moving in a fluid
Did the Wright brothers invention work and why?
Their aircraft? Yep. It was a biplane, and it produced lift by moving air over an airfoil. The effect of an airfoil is described in part by the Bernoulli Principle.
Why wings are shaped like airfoil?
Wings are airfoils. The purpose of the airfoil it to accelerate air over the top of the wing and create an area of low pressure, which produces lift.
How much lift will a wing generate?
A wing will generate lift according to the following equation: L = ½ A C ρ v² A = wing area C = lift coefficient ρ = air density v = air speed The lift coefficient C is a function of Angle of Attack (AOA), which is the angle between the wing's chord line and the relative wind. The greater the angle, the greater the lift coefficient up until the critical AOA where the wing begins to stall and lose lift. The lift coefficient is also a function of wing aspect ratio and will be specific to a certain airfoil shape.
Which part of the wing produces more lift the upper part or the lower part?
Tough question to answer as asked. In normal airfoils, the top of the airfoil is thicker and curved and it is this thicker, curved section that causes the air to speed up as it flows over it. This increase in airspeed over the top of the airfoil results in a lowering of the pressure and it is that pressure differential between the top and the bottom of the airfoil that is known as lift. However, while the shape of the top of the wing is what generates lift, the force itself is applied to the lower part of the wing, hence the airfoil rises. I guess the best answer would be to say it is produced by the upper part of the airfoil and is applied to the lower part of the airfoil. Look up Bernoulli for a more detailed discussion.
