In this series from IHS ESDU, challenge questions will be posted for the community. Some questions may require calculations and others are general knowledge questions.

Here's this week's question:

For an elliptically loaded aircraft wing, will adding a vertical winglet having a length of 15% wingspan increase or decrease the lift/drag ratio for a typical transport aircraft?


Check back soon for the solution to this question! Visit the IHS ESDU website for more information about the validated design methods, or to request a trial subscription.

Decrease. Elliptically loaded wing has optimum L/D ratio.
