Since increasing aspect ratio while maintaining wing area decreases chord, one can expect Reynolds number to decrease. Are there cases in which the resulting increased coefficient of friction would outweigh the induced drag benefits of the higher aspect ratio? Edit: In response to @Zeus's comment, let's presume we're talking about glider speeds, so something between 70kph and 250kph.

    $\begingroup$ You should restrict the conditions further. Otherwise the answer will be: yes, of course. For example, at zero angle of attack (no induced drag benefit), or at supersonic speeds (wave drag). $\endgroup$ – Zeus Oct 27 '20 at 23:17
