lift


lift
i. That component of the aerodynamic forces acting on the wing or airfoil section that opposes gravity. It is perpendicular to the flight path or free-stream flow. Simply put, it is the difference between the static pressure on the airfoil lower surface and that on the airfoil top surface. Lift (L) = coefficient of lift (CL ) 1/2 × density (ρ) × velocity square (V2 ) × surface area of airfoil (S), or L = CL 1/2ρV2 S.
ii. The whole or part of an airborne operation, as in the Berlin Airlift. The terms first lift and second lift also are used in the same sense.
