The angle between the chord line of an airfoil and the airflow over it; one of the determiners of the amount of lift produced by an airfoil
The amount of pitch at which an airfoil is flying By adjusting the angle of attack, the efficiency of the wing/blade is effected More precisely, the angle between the chord of an airfoil and the wind
Also designated as AoA It is the angle difference between the wing-chord line measurement and the relative wind
1 hydrodynamically, the designed angle between the planing surface of the sponson and the surface of the water, measured fore and aft
The angle between the relative wind direction and an imaginary line through the center of a flying surface, such as a rocket fin; generally, as the angle of attack increases (raising the forward edge of the surface) so does lift and drag
Angle between the reference axis (x-axis) of an airfoil and the onset flow direction Variable, depending of flow direction and flight condition
in the theory of airplane wings, the angle between the wing profile (roughly, measured along its bottom) and the wing's motion relative to the surrounding air
