The values of lift slope for elliptic wing (ae) and general planform wing (a) is less than that for airfoil (a0).Mark the false statement.

Flow over Airfoils over Finite Wing topics include: Downwash and induced drag, vortex filament, biot savart law, helmholtz theorem, prandtl’s classical lifting line and lifting surface theory.

Flow over Airfoils over Finite Wing topics include: Downwash and induced drag, vortex filament, biot savart law, helmholtz theorem, prandtl’s classical lifting line and lifting surface theory.

Flow over a finite wing is three-dimensional, while flow over an airfoil is two-dimensional. The flow tends to leak around the wing tips, creating a trailing vortex at each tip. 

The flow over the wing creates a circulatory motion that trails downstream. This motion creates wing-tip vortices that induce a small downward component of air velocity. This downward component is called downwash. The presence of downwash creates drag, which is defined as induced drag. 

Finite wings experience 3-dimensional effects of airflow not experienced by infinite airfoils: downwash and induced drag.
