How Airplanes Fly: Lift and Circulation

... wing by the air is −ρhwv∞vy which is > 0 because vy < 0. A vertical section of the closed path that includes vy contributes hvy < 0 to Γ. Thus the lifting force/length is Fy/w = −ρv∞Γ > 0. In 1902 Martin Kutta in Germany published “Lifting forces in flowing fluids,” which related lift to circulation ...

How an Airfoil Generates Lift

... There is a limiting case for how great an angle of attack can be in order to generate lift. As the angle of attack increases above 15 degrees for most airfoils flow separation begins to occur. This reduces circulation which decreases the pressure distribution around the airfoil. Consequently, the re ...

A fluid flowing past the surface of a body exerts a force on it. Lift is the component of this force that is perpendicular to the oncoming flow direction. It contrasts with the drag force, which is the component of the surface force parallel to the flow direction. If the fluid is air, the force is called an aerodynamic force. In water, it is called a hydrodynamic force.
