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
chord — An imaginary straight line joining the center of the leading and trailing edges of a cross section of an airfoil. The mean chord is used as a reference datum for laying out the curve of the airfoil. Also called a chord line … Aviation dictionary
chord line — An imaginary line joining the center of the leading and trailing edge of an airfoil. It is used as a reference or datum for laying out the curve of the airfoil. Also referred to as a chord. See chord length … Aviation dictionary
quarter-chord — The locus of all points on an airfoil or wing lying at a 25% chord. These measurements are made in the plane parallel roots along the longitudinal axis of an aircraft. Normally, the reference wing is in a clean configuration, but it includes… … Aviation dictionary
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
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
Aerodynamic center — The aerodynamic center of an airfoil moving through a fluid is the point at which the pitching moment coefficient for the airfoil does not vary with lift coefficient i.e. angle of attackcite web last = Benson first = Tom coauthors = year = 2006… … 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
Propeller — A propeller is essentially a type of fan which transmits power by converting rotational motion into thrust for propulsion of a vehicle such as an aircraft, ship, or submarine through a mass such as water or air, by rotating two or more twisted… … Wikipedia
