HGs of very low aspect ratio have probably not been explored as deeply as very low aspect ratio paper hand-toss gliders. Design trends went the other direction for HGs for some good reasons. But VLARHG may yet have some play for recreational hang gliding. Cayley's glider https://disciplesofflight.com/the-fathe ... aeroplane/ was fairly low in aspect ratio. But one may easily envision gliders of every less aspect ratio than Cayley's glider.
Maybe explore a HG that has a span of 8 ft while having a chord of 20 ft. A.R.: 8/20= 0.4 What glide ratio might we obtain from a judicious design? Drag coefficients will be critical.
Here is a video regarding "lifting bodies" of low aspect
This topic thread could discuss and maybe forward VLARHG. Is there a fun future for VLARHG? Not sure.
