How aspect ratio related to induced drag?

Aspect ratio, defined as the ratio of a wing's span to its average chord, significantly influences induced drag. Higher aspect ratiOS generally lead to lower induced drag because they promote more efficient airflow over the wings and reduce vortex formation at the wingtips. This is due to the increased span allowing for a more streamlined shape, which minimizes lift-induced drag. Conversely, lower aspect ratiOS result in higher induced drag due to greater vortex strength and energy loss.
