The catenary and satenary curves, which frame the leading and trailing edges of this flying wing, run between the x values negative & positive SquareRoot[2] ; in part because the form is more-or-less square that way, and in part for personal preference . (A viable wing might also be developed between the x values of -1 and 1)

From the center to each end, the exponent used for the second and third terms of the airfoil's y value calculation is varied between 2pi, (yielding the narrower curve), and pi . Though these values are arbitrary, the intent is to provide stall protection, to add lift, durability, and directional stability . All airfoil sections are oriented forward
