🌬️ Wind Tunnel Simulator: Airfoil Lift, Drag, Smoke Streaks and Pressure Taps

Run any NACA 4-digit airfoil in a Blender-built suction wind tunnel: a real Hess-Smith panel-method solver (Kutta condition) gives Cp on 16 pressure taps, lift, moment and smoke streaklines, with an empirical Thwaites/Stratford stall and friction-drag layer, a force balance in newtons, polar sweeps and in-page checks against thin-airfoil theory, the cylinder solution and Kutta-Joukowski. Unlike the existing wind-tunnel pages it solves the flow for user-defined NACA sections instead of animating a canned field.
