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
airfoil/aerofoil — A body of such shape that the force exerted on it by its motion through a fluid has a larger component normal, or perpendicular, to the direction of the motion than along the direction of the motion. This force is in the form of lift or thrust. A … Aviation dictionary

Supercritical airfoil — it has since been mainly applied to increase the fuel efficiency of many high subsonic aircraft. Research in 1940 by DVL s K. A. Kawalki led to subsonic profiles very similar to the supercritical profiles, which was the basis for the objection in … 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
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
Lift-induced drag — In aerodynamics, lift induced drag, induced drag, vortex drag, or sometimes drag due to lift, is a drag force that occurs whenever a moving object redirects the airflow coming at it. This drag force occurs in airplanes due to wings or a lifting… … Wikipedia

Leading edge slot — The leading edge slot is an aerodynamic feature of the wing of some airplanes to reduce the stall speed and promote good low speed handling qualities. A leading edge slot is a span wise gap in each wing, allowing air to flow from below the wing… … Wikipedia
