2. Lift-to-drag ratio - Wikipedia

   en.wikipedia.org/wiki/Lift-to-drag_ratio

   Most importantly, the maximum lift-to-drag ratio is independent of the weight of the aircraft, the area of the wing, or the wing loading. It can be shown that two main drivers of maximum lift-to-drag ratio for a fixed wing aircraft are wingspan and total wetted area. One method for estimating the zero-lift drag coefficient of an aircraft is the ...

   A Gabrielli–von Karman diagram with the y-axis being the lift-to-drag ratio, which is the inverse of specific resistance. The von Kármán–Gabrielli diagram (also Gabrielli–von Kármán diagram , GvK diagram ) is a diagram which compares the efficiency of transportation methods by plotting specific tractive force , or specific resistance ...

6. Aerodynamic force - Wikipedia

   en.wikipedia.org/wiki/Aerodynamic_force

   The aerodynamic force is the resultant vector from adding the lift vector, perpendicular to the flow direction, and the drag vector, parallel to the flow direction. Forces on an aerofoil . In fluid mechanics , an aerodynamic force is a force exerted on a body by the air (or other gas ) in which the body is immersed, and is due to the relative ...

7. Lift coefficient - Wikipedia

   en.wikipedia.org/wiki/Lift_coefficient

   It is also useful to show the relationship between section lift coefficient and drag coefficient. The section lift coefficient is based on two-dimensional flow over a wing of infinite span and non-varying cross-section so the lift is independent of spanwise effects and is defined in terms of ′, the lift force per unit span of the wing. The ...
