I working on a new airfoil design. Please tell me the airfoil having highest lift to drag ratio, I need it for comparison.

You realize there are hundreds and hundreds of airfoil designs, right?

I doubt anyone knows that off the top of their head, and you can research it as easily as any of us.

There occurs various hybrid wings; however currently the most researched is Morphing Wings

Search NACA aerofoils one of them is NACA 64A309 Hydrofoils,try analysing different NACA aerofoils in XFLR5 software, its free easy to use..

high lift airfoils that are commonly used in aerodesign competition is the Selig 1223 and Epler 423, due to the great lift to drag ratio...

Good luck controlling a blended wing body design though. You need sophisticated, computerized control systems to successfully keep such designs airborne and stable.

OP, research the airfoils used by high performance gliders...
