The Ultra-High Aspect Ratio Wing (UHARW) concept is a promising configuration to achieve future sustainable aviation goals. Twin-Fuselage (TF) and Strut-Braced-Wing (SBW) configurations are characterized by smaller structural bending moments and shear forces in the wing and are promising concepts for realizing UHARW designs. This paper addresses the aerostructural optimization problem of TF and SBW configurations with UHARW by using a coupled adjoint aerostructural optimization tool, which is composed of a geometrically nonlinear structural solver and a quasi-three-dimensional Natural Laminar Flow (NLF) aerodynamic solver. The optimization results show a significant improvement in fuel efficiency and performance, with a 13% and 10% reduction in fuel mass for the TF and SBW aircraft, respectively. The compressibility drag of the wing is greatly reduced and the NLF range of both upper and lower wing surfaces is expanded during the optimization. Besides, the aerostructural optimization finds that the SBW configuration is more conducive to realizing UHARW design compared with the TF configuration for the medium-range mission studied in this work.

The Ultra-High Aspect Ratio Wing (UHARW) concept is a promising configuration to achieve future sustainable aviation goals. Twin-Fuselage (TF) and Strut-Braced-Wing (SBW) configurations are characterized by smaller structural bending moments and shear forces in the wing and are promising concepts for realizing UHARW designs. This paper addresses the aerostructural optimization problem of TF and SBW configurations with UHARW by using a coupled adjoint aerostructural optimization tool, which is composed of a geometrically nonlinear structural solver and a quasi-three-dimensional Natural Laminar Flow (NLF) aerodynamic solver. The optimization results show a significant improvement in fuel efficiency and performance, with a 13% and 10% reduction in fuel mass for the TF and SBW aircraft, respectively. The compressibility drag of the wing is greatly reduced and the NLF range of both upper and lower wing surfaces is expanded during the optimization. Besides, the aerostructural optimization finds that the SBW configuration is more conducive to realizing UHARW design compared with the TF configuration for the medium-range mission studied in this work.
