Airfoils: A Short History - FLYING Magazine

Airfoils are highly-efficient lifting shapes, able to generate more lift than similarly sized flat plates of the same area, and able to generate lift with significantly less drag. Airfoils are used in the design of aircraft, propellers, rotor blades, wind turbines and other applications of aeronautical engineering. See more An airfoil (American English) or aerofoil (British English) is the cross-sectional shape of an object whose motion through a gas is capable of generating significant lift, such as a wing, a sail, or the blades of propeller, rotor, … See more The various terms related to airfoils are defined below: • The suction surface (a.k.a. upper surface) is generally associated with higher velocity and lower static pressure. • The pressure surface (a.k.a. lower surface) has a comparatively … See more Thin airfoil theory is a simple theory of airfoils that relates angle of attack to lift for incompressible, inviscid flows. It was devised by German mathematician Max Munk and … See more • Circulation control wing • Hydrofoil • Kline–Fogleman airfoil See more The wings and stabilizers of fixed-wing aircraft, as well as helicopter rotor blades, are built with airfoil-shaped cross sections. Airfoils are also found in propellers, See more The airfoil is modeled as a thin lifting mean-line (camber line). The mean-line, y(x), is considered to produce a distribution of vorticity $${\displaystyle \gamma (s)}$$ along the line, s. By the Kutta condition, the vorticity is zero at the trailing edge.
