  • Zero-lift drag coefficient — In aerodynamics, the zero lift drag coefficient CD,0 is a dimensionless parameter which relates an aircraft s zero lift drag force to its size, speed, and flying altitude. Mathematically, zero lift drag coefficient is defined as CD,0 = CD − CD,i …   Wikipedia

  • Zero lift axis — When symmetric aerofoils are moving parallel to the chord line of the aerofoil, zero lift is generated. However, when cambered aerofoils are moving parallel to the chord line, lift is generated. (See diagram at right.)A cambered aerofoil… …   Wikipedia

  • zero-lift angle — The angle of attack at which an airfoil does not produce any lift. Its value is generally less than zero unless the airfoil is symmetrical. Pressure distribution on an airfoil at the angle for zero lift (–3°) …   Aviation dictionary

  • zero-lift chord — A chord taken through the trailing edge of an airfoil in the direction of the relative wind when the airfoil is at a zero lift angle of attack. See zero lift angle …   Aviation dictionary

  • zero-lift line — A line through an airfoil, along which the relative airflow produces zero lift. This line is drawn through the trailing edge of an airfoil parallel to the relative airflow when the lift generated by the airfoil is zero …   Aviation dictionary

  • 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

  • Lift-to-drag ratio — In aerodynamics, the lift to drag ratio, or L/D ratio ( ell over dee in the US, ell dee in the UK), is the amount of lift generated by a wing or vehicle, divided by the drag it creates by moving through the air. A higher or more favorable L/D… …   Wikipedia
