minimum area foot land glider

jgeating

I am looking into how small (minimize surface area) a glider could be to be foot land. I would like to look into possibly designing and or building a backpack deployable glider, but first would just like to design a non-deployable glider with minimal surface area.

To do this, currently my only thought is to start at a typical hang glider. I would like to be able to look up specific data and specifications of modern (or older) hang gliders, primarily their airfoil, surface area, Cl to Cd ratio, Cl to wing area, and wing loading. Because modern hang gliders are designed to have good glide ratios, and thus high Cl to Cd ratios, my primary advantage would be that I can have a horrible Cl/Cd ratio, but a much better Cl/wing area ratio, allowing me to have a smaller wing. Also, I am assuming the pilot can land at around 10 mph, as opposed to full stops like most hang gliders. These two combined, I would like to see if it is possible to fit the corresponding wing in a backpack.

Could anyone give me any tips. For now, I would really like to know if there is a standard or primary resource for hang glider airfoils. For calculations, initially I just plan on keeping lift as a constant and varying the area, Cl/Cd, and Cl/area interchangeable to minimize area.

I am a second year mechanical engineer, but I would like to get more into aeronautical engineering. Any advice will be much appreciated.

Thanks,
