The Blended-Wing-Body (BWB) aircraft, renowned for its superior lift-to-drag characteristics and structural efficiency, represents a significant developmental direction for future civil and specialized aircraft. However, its complex aerodynamic shape and pronounced longitudinal coupling characteristics pose substantial challenges for aerodynamic design and performance optimization. This paper aims to establish a high-fidelity, low-variable parametric model of the BWB configuration based on the Class-Shape-Transformation (CST) method. Furthermore, it conducts a multi-objective optimization reconfiguration study centered on achieving "three-point convergence" and the "aft-shift of the pitch moment break." The goal is to systematically enhance the BWB's comprehensive aerodynamic performance and handling stability.
