There is indeed a formula to calculate induced drag. For a planar wing with elliptical lift distribution, induced drag is given by; However, for non-elliptical lift distribution, the induced drag is calculated by divinding the above result with span efficiency factor e. The span efficiency factor for elliptical lift distribution is equal to 1.

Comsol continuity boundary conditionJul 16, 2020 · As E goes down, induced drag goes up by a factor of 1/E. For example, a wing with a span efficiency of 85% would have 1/0.85 or 1.176 times the induced drag of a perfect wing. Classical theory tells us that an ideal wing has an elliptical-shaped spanwise distribution of lift. Accordingly, E=1.0 represents a wing with an elliptical span loading.

- An elliptical wing is a wing planform shape that minimizes induced drag. [1] Elliptical taper shortens the chord near the wingtips in such a way that all parts of the wing experience equivalent downwash, and lift at the wing tips is essentially zero, improving aerodynamic efficiency due to a greater Oswald efficiency number in the induced drag equation.
- Elliptical wing planforms produces the lowest induced drag (all other relevant factors held constant). Excluding constants, the coefficient of induced drag (CDI) is the ratio of CL square and Aspect Ratio. CDI = CL^2 / Aspect Ratio The induced drag coefficient, CDI is proportional with CL square. Induced Drag Formula For an elliptical wing
- This downwash component is caused by the induced flow from the trailing vortex sheet. where is the 3-D wing angle of attack, t is the wing twist angle and w i is the velocity induced by trailing vortex sheet. The vortex strength distribution in the trailing sheet will be a function of the changes in vortex strength along the wing span.
- Simple explanation - a true elliptical wing planform generated the least possible Induced drag when compared to rectangular or trapezoidal planforms. That being said, wing twist to achieve wing tip control near stall (washout) negated some of the advantages. The Spit designed wing twist into the wing for just that pupose.

- The purported virtue of the elliptical wing was that, theoretically at least, it would generate the least possible lift-dependent, or induced, drag. Induced drag is the drag incurred by the mere action of generating lift, as opposed to the drag due to skin friction (parasite drag) and to turbulent eddies left behind as the airplane passes.
- 2. This is a design question for an elliptical wing, where we will consider the cost of fuel expended due to induced drag. By designing a wing where the costs from induced drag are kept reasonable, it means that less fuel is used, which means reduced emissions (pollution.
