1) hydrodynamically, the designed angle between the planing surface of the sponson and the surface of the water, measured fore and aft; 2) aerodynamically, the angle between the chordline of a hydroplane's wing and the apparent wind.
the angle of the wing (when viewed from the end) in relation to the horizontal airflow when the airplane is flying. Nothing to do with your incoming trajectory when trying to cut the tail off your friend's model in aerial combat games.
The angle between the chord line of an aerofoil and the relative airstream, no matter what the angle of the aeroplane. This is also the True Angle of Downwash - the angle through which the airstream relative to the main axis of the aeroplane is deflected by the aerofoil.
The angle measured between the chord line of an airfoil (wing or rotor) and the relative wind (RW) of airflow over the airfoil. (For rotor blades, rotational relative wind (RRW) is used.) Report this Word See also: AOA | Harrier | Stall | Washout Added by: mkranitz
in flight, the angle of attack (AoA) is essentially the incidental angle at which air hits the wing. All paragliders have a naturally "positive" AoA, i.e. the leading edge is higher than the trailing edge in flight. The only flight instrument used by the Wright brothers on their first airplane was an angle of attack indicator.
The amount of twist in a wing; a positive angle of attack sees the bottom of the wing pointing slightly in the direction of rotation. A significant portion of the lift of a boomerang arises from angle of attack, including the built-in geometric angle of attack. Reduced angle of attack is sometimes referred to as 'washout'.
Angle of attack (\alpha, Greek letter alpha) is a term used in aerodynamics to describe the angle between the airfoil's chord line and the direction of airflow wind, effectively the direction in which the aircraft is currently moving. It can be described as the angle between where the wing is pointing and where it is going.
The angle at which the clubhead descends toward the golf ball on the downswing. A steep angle of attack is more likely from an upright swing and a shallow angle of attack comes from a swing with a flatter swing plane.
