Lifting-line theory - Wikipedia

In aerodynamics, the lift-to-drag ratio (or L/D ratio) is the lift generated by an aerodynamic body such as an aerofoil or aircraft, divided by the aerodynamic drag caused by moving through air. It describes the aerodynamic efficiency under given flight conditions. The L/D ratio for any given body will vary according to these flight conditions.

Airplanes are the most common application of lift and drag forces. In order to understand how airplanes take off and keep flying, we need to understand how lift, drag, and pitch can influence an airplane’s motion through air. dish on demand logoWebCoefficient of lift and drag are not constants (obviously). They are a property of airfoil geometry and are constant for a given airfoil. Take a Naca4412 airfoil. It has a given shape. Put it at the wind at a different angle, and it’s geometry (relative to the airflow) changes. So the lift changes based off geometry. dishomion photography
