abstract = "Innovative configurations such as truss-brass wing (TBW) offer the potential of greatly reducing the fuel consumption of future greener transport aircraft. Previous study suggests that the benefit of a TBW configuration needs to be fully exploited by multidisciplinary design optimization (MDO). This paper conducted a MDO study of the TBW configurations by integrating the aerodynamic and structure disciplines. For aerodynamic discipline, the induced drag, wave drag, friction drag as well as interference drag due to wing, strut and jury is investigated; for structural discipline, the box-beam model is used and full-stress optimization is utilized for sizing. The aerodynamic/structural analysis is integrated within an efficient surrogate-based optimization framework and the multi-objective optimization of the wing, strut and jury is performed. The Pareto front results show that TBW with 2 juries is the most effective configuration with respect to the aerodynamic lift-to-drag ratio and structural weight.",
