Delta plane airfoil
As I am not a crack in aerodynamics I have the following question: what would be an appropriate low drag, laminar airfoil for a fast delta?
As the delta plane has a large root chord, the airfoil should be suited for Reynolds numbers in the range of 4.000.000-5.000.000.
Also, what would be the aerodynamic effect of "stretching" an airfoil to reduce thickness?
