Induced drag

Definitions

• Drag that is the consequence of developing lift with a finite-span wing. It can be represented by a vector that results from the difference between total and vertical lift.
• That part of the total drag that is created by the production of lift.
• Drag caused by the same factors that produce lift; its amount varies inversely with airspeed. As airspeed decreases, the angle of attack must increase, in turn increasing induced drag.
• That part of total drag which is created by the production of lift. Induced drag increases with a decrease in airspeed.
