3lift/drag ratio — The ratio of the coefficient of lift to the coefficient of drag of an airfoil at various angles of attack. It is a measure of the airfoil’s efficiency. The angle of attack that gives the best lift by drag ratio is the most efficient angle of… …
4Zero-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 …
5zero-lift drag — The drag when an aircraft is flying at the zero lift angle of attack …
6Lift-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… …
7Drag coefficient — In fluid dynamics, the drag coefficient (commonly denoted as: cd, cx or cw) is a dimensionless quantity that is used to quantify the drag or resistance of an object in a fluid environment such as air or water. It is used in the drag equation,… …
8lift wires — Wires installed between the wings of a biplane to support the wings and hold them in alignment against the forces of lift. Lift wires run from the inboard end of the lower wing to the interplane struts on the upper wing. See landing wires.… …
