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

Vortex lift — is a form of lift generated by delta wings operating at high angles of attack. How it worksVortex lift works by capturing vortices generated from the sharply swept leading edge of the wing. The vortex, formed roughly parallel to the leading edge… … Wikipedia
Vortex induced vibration — Vortex induced vibrations (VIV) are motions induced on bodies facing an external flow by periodical irregularities on this flow. The classical example is the VIV of an underwater cylinder. You can see how this happens by putting a cylinder into… … Wikipedia
Vortex lattice method — The Vortex lattice method, (VLM), is a numerical, Computational fluid dynamics, method used mainly in the early stages of aircraft design and in aerodynamic education at university level. The VLM models the lifting surfaces, such as a wing, of an … Wikipedia
Vortex — A vortex (pl. vortices ) is a spinning, often turbulent, flow of fluid. Any spiral motion with closed streamlines is vortex flow. The motion of the fluid swirling rapidly around a center is called a vortex. The speed and rate of rotation of the… … Wikipedia
Vortex generator — A vortex generator is an aerodynamic surface, consisting of a small vane that creates a vortex.Peppler, I.L.: From The Ground Up , page 23. Aviation Publishers Co. Limited, Ottawa Ontario, Twenty Seventh Revised Edition, 1996. ISBN 09690054 9 0]… … Wikipedia
Drag 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,… … Wikipedia
Drag equation — In fluid dynamics, the drag equation is a practical formula used to calculate the force of drag experienced by an object due to movement through a fully enclosing fluid. The equation is attributed to Lord Rayleigh, who originally used L2 in place … Wikipedia

Lift-induced drag — In aerodynamics, lift induced drag, induced drag, vortex drag, or sometimes drag due to lift, is a drag force that occurs whenever a moving object redirects the airflow coming at it. This drag force occurs in airplanes due to wings or a lifting… … Wikipedia
