The angle formed between the direction of air movement as it approaches an airfoil and its direction as it leaves.
An airfoil produces lift by deflecting air downward. The upward component of lift is equal to the downward component created by the mass of the down-washed air.
Industry:Aviation
The angle formed between the face of a propeller blade and its plane of rotation. Blade angle is normally specified at a particular blade station.
Industry:Aviation
The angle formed between the plane of rotation of a helicopter rotor blade when it is producing lift, and a line perpendicular to the rotor shaft.
The degree of the coning angle is determined by the relationship between the centrifugal force acting on the blades and the aerodynamic lift produced by the blades.
Industry:Aviation
The angle formed between the spanwise axis of a helicopter rotor blade, when the rotor system is producing lift, and a plane at right angles to the rotor mast.
The coning angle is caused by the relationship between the centrifugal force acting on the rotor blade and the lift produced by the blades.
Industry:Aviation
The angle formed between the spanwise axis of the rotor blades, when the blades are not rotating, and the plane of rotation of the blades perpendicular to the rotor shaft.
The only force acting on the blade to cause droop is gravity.
Industry:Aviation
The angle formed by one surface with another surface when the angle is not a right angle.
Industry:Aviation
The angle formed by the lateral axis of an aircraft and a horizontal plane.
Industry:Aviation
The angle of attack at which air flowing over an aerodynamic surface no longer flows smoothly, but breaks away and forms a turbulent flow (it burbles).
Industry:Aviation
The angle of deflection of an aileron from its neutral, or trailing, position. Aileron angle is positive when the trailing edge of the aileron is below its neutral position and negative when it is above neutral.
Industry:Aviation
The angle, measured at the receiving antenna, between the line of propagation of a radio wave and the surface of the earth.
