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 that redirect air to cause a
downforce. With other parameters remaining the same, induced drag increases as the
angle of attack increases.
