Enicalyth,
Reference your calculations, I think I understand how you did them, but may I ask how the 7% compressibility was factored in? Is Cd just multiplied by 1.07 with CL left unchanged?
Are values of Cdo and e readily available for other aircraft, and is this fascinating data available via special flight test papers/aerodynamic studies?
I'd love to know more!! Anything available to email me?
