Lift-to-drag ratio - Wikipedia

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.

Aerodynamic Lift and Drag and the Theory of Flight

WebLift and drag are the aerodynamic forces that an object in a fluid will experience due to its motion. The fluid may be gas or liquid. If the fluid is gas then the forces are called … WebJul 28, 2024 · This additional source of drag is called the induced drag or drag due to lift. Induced drag occurs because of the distribution of lift across the span of the wing. Because of pressure differences above and below the wing, the air on the bottom of the wing is drawn onto the top near the wing tips.
