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

induced drag — That part of total drag caused by the same aerodynamic factors that produce lift. Total drag is the sum of the parasite drag and the induced drag. Induced drag is dependent on the airfoil shape, its lift coefficient (CL 2 ), velocity (1/V2 ),… … Aviation dictionary
vortex drag — That part of total drag caused by the same aerodynamic factors that produce lift. Vortex drag is dependent on the airfoil shape, its lift coefficient (CL 2), velocity (1/V 2), weight (W 2), and aspect ratio (1/A). Also called induced drag … Aviation dictionary

Ground effect vehicle — A ground effect vehicle, wing in ground effect vehicle (WIG), flarecraft, sea skimmer, ekranoplan, or wing in surface effect ship (WISE) is a vehicle that attains level flight near the surface of the Earth, made possible by a cushion of high… … Wikipedia
Wing — A wing is a surface used to produce lift for flight through the air or another gaseous medium. The wing shape is usually an airfoil. The word originally referred only to the foremost limbs of birds, but has been extended to include the wings of… … Wikipedia
