Lift (force) - Wikipedia
WEBLift is defined as the component of the aerodynamic force that is perpendicular to the flow direction, and drag is the component that is parallel to the flow direction. A fluid flowing around the surface of a solid object applies a force on it.
What is Lift? - Glenn Research Center
WEBJul 21, 2022 · Lift is a mechanical aerodynamic force produced by the motion of the airplane through the air. Because lift is a force, it is a vector quantity, having both a magnitude and a direction associated with it. Lift acts through the center of pressure of the object and is directed perpendicular to the flow direction.
