Induced drag is a type of drag generated by the production of lift on a finite wing. When an aircraft generates lift, it creates vortices at the wingtips due to the pressure difference between the upper and lower surfaces of the wing.
Where:
- = induced drag
- = lift
- = air density
- = velocity
- = wing area
- = pi (approximately 3.14159)
- = Oswald efficiency factor
- = aspect ratio
