Oswald Efficiency for Non-Elliptical Wing Calculator

Oswald Efficiency


e is the Oswald Efficiency

δ is the Lift Efficiency Factor

Oswald Efficiency, similar to the span efficiency, is a correction factor that represents the change in drag with lift of a three-dimensional wing or airplane, as compared with an ideal wing having the same Aspect Ratio and an elliptical lift distribution.
