The tailless flying wing design encounters a significant challenge from the lack of longitudinal control. This paper establishes an efficient robust aerodynamic/stealth design optimization method based on the proposed gradient-enhanced multi-fidelity polynomial chaos-Kriging model. This proposed method is validated to significantly improve the aerodynamic/stealth/control performance of a tailless flying wing.
