چکیده

Considering the drag-divergence performance as a constraint, this paper presents multi-point aero-structural design optimization of wings on wing-body-tail-engine configuration long-range dual-aisle civil aircraft by using gradient-based method based discrete adjoint method. Firstly, accuracy coupled analysis used in was validated with DLR-F6 wing-body configuration. Then wing is offered. The drag coefficient optimized every state decreased, which reduced 13.67 counts at cruise condition, difference from Mach 0.85 to 0.87 decreased 28.52 18.98 counts, indicating its has been improved undoubtedly. Finally, we compared among configuration, single-point aerodynamic and structural results show that considering great potential gain better comprehensive practical single discipline.
