Hi!
I guess that one of the mot basic possible structures, and hopefully safest, would be a hang glider with battens. It is not uncommon to see, basic hang glider structures with a perfect delta planform. However a delta shape, is very unusual in conventional three axis airplanes. From what I understand, a pointed tip wing, albeit it can be found in birds, does not behave well in stall, that might explain why it is rare in conventional sport airplanes. The closest airplane that comes to mind, with an almost perfect delta shape is the Dassault Mirage, but it is a supersonic aircraft. So probably the wing planform is more dictated by its high speed, rather than its stall characteristics.
So, how does a perfect delta wing planform works well for low stall speeds in a hang glider, is it because of the low wing loading?
Thanks in advance for your comments!
