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
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 — /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 …
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
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
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
Center of pressure — The center of pressure is the point on a body where the sum total of the aerodynamic pressure field acts, causing a force and no moment about that point. Mathematically it can be said that the net pressure force on the body acts through this… … Wikipedia
Longitudinal static stability — is important in determining whether an aircraft will be able to fly as intended. Static stability As any vehicle moves it will be subjected to minor changes in the forces that act on it, and in its speed. * If such a change causes further changes … Wikipedia
