Drag due to lift factor

Webaerodynamic force acting over the entire wing. This additional force is called induced dragbecause it faces downstream and has been "induced" by the action of the tip vortices. It is also called "drag due to lift" because it … Webdrag-due-to-liftcoefficient for this condition is C1; tan a. For 100 percent suction, the drag-due-to-liftcoefficient is the potential flow induced vortex drag and is indicated as CD,~ in the vector diagram. The drag-due-to-lift coefficients for 100 percent suction were determined from a modified Multhopp subsonic lifting surface theory.

In aerodynamics, lift-induced drag, induced drag, vortex drag, or sometimes drag due to lift, is an aerodynamic 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 body redirecting air to cause lift and also in cars with airfoil wings … See more The total aerodynamic force acting on a body is usually thought of as having two components, lift and drag. By definition, the component of force parallel to the oncoming flow is called drag; and the component … See more Induced drag causes wingtip vortices. When producing lift, air below the wing is at a higher pressure than the air pressure above the wing. On a wing of finite span, this pressure difference causes air to flow from the lower surface, around the wingtip, towards the upper … See more In 1891, Samuel Langley published the results of his experiments on various flat plates.
