This work aims to find the optimal combination of cruise altitude and wing sweep angle for a transonic strut-braced-wing regional jet with natural laminar flow operating at a cruise speed of Mach 0.78. Using aerodynamic shape optimization with integrated transition prediction, cruise drag can be minimized while ensuring a design that is robust to variations in cruise speed and lift coefficient.
