Angle of attack — In this diagram, the black lines represent the flow of a fluid around a two dimensional airfoil shape. The angle α is the angle of attack. Angle of attack (AOA, α, Greek letter alpha) is a term used in fluid dynamics to describe the angle between … Wikipedia
Lift (force) — For other uses, see Lift. Boeing 747 8F landing A fluid flowing past the surface of a body exerts a surface force on it. Lift is the component of this force that is perpendicular to the … Wikipedia
Lift coefficient — The lift coefficient ( or ) is a dimensionless coefficient that relates the lift generated by a lifting body, the dynamic pressure of the fluid flow around the body, and a reference area associated with the body. A lifting body is a foil or a… … Wikipedia
Lift-to-drag ratio — In aerodynamics, the lift to drag ratio, or L/D ratio ( ell over dee in the US, ell dee in the UK), is the amount of lift generated by a wing or vehicle, divided by the drag it creates by moving through the air. A higher or more favorable L/D… … Wikipedia
critical angle — 1. Optics. the minimum angle of incidence beyond which total internal reflection occurs for light traveling from a medium of higher to one of lower index of refraction; the angle of incidence for which refracted rays emerge tangent to the surface … Universalium
stalling angle — The angle of attack at which the flow of air over the wing begins to separate from the wing surface, resulting in a significant reduction in the lift and an increase in the drag. The lift coefficient of an airfoil is maximum at this angle and… … Aviation dictionary
stalling angle — /ˈstɔlɪŋ ˌæŋgəl/ (say stawling .angguhl) noun Aeronautics the angle of attack providing maximum lift for an aircraft; below this angle the airflow becomes turbulent, leading to an abrupt loss of lift. See angle of attack. Also, stall angle …
Critical angle — can refer to: Critical angle (optics) the angle of incidence above which total internal reflection occurs Critical angle of attack, in aerodynamics; the angle of attack which produces the maximum lift coefficient Critical angle of repose, in… … Wikipedia
Stall (flight) — For other uses, see stall. In fluid dynamics, a stall is a reduction in the lift coefficient generated by a foil as angle of attack increases. This occurs when the critical angle of attack of the foil is exceeded. The critical angle of attack is… … Wikipedia
Airfoil — An airfoil (in American English) or aerofoil (in British English) is the shape of a wing or blade (of a propeller, rotor or turbine) or sail as seen in cross section. An airfoil shaped body moved through a fluid produces a force perpendicular to… … Wikipedia
