A geometrically nonlinear structural model for aerostructural optimization of ultra-high aspect ratio composite wings
A geometrically nonlinear structural model for aerostructural optimization of ultra-high aspect ratio composite wings
This paper presents the development of a coupled-adjoint aerostructural optimizati on tool for strut-braced Ultra High Aspect Ratio (UHAR) wings made of composite materials . The formulation of the structure model is based on thin to moderately thick composi te wings with special considerations applicable to the large deformations of the flexible UHAR wings with small strains. Transverse shear deformations and moderate twist angles are considered, making the model novel for the preliminary design of such structures. The finite element model has been validated based on available data in the literature. The coupled aerostructural analysis and the coupled-adjoint sensitivity analysis have been verified based on the cantilever wing design of A320 like aircraft. Then, the tool has been applied to optimize a strut-braced with a high aspect ratio.

Abstract
This paper presents the development of a coupled-adjoint aerostructural optimizati on tool for strut-braced Ultra High Aspect Ratio (UHAR) wings made of composite materials . The formulation of the structure model is based on thin to moderately thick composi te wings with special considerations applicable to the large deformations of the flexible UHAR wings with small strains. Transverse shear deformations and moderate twist angles are considered, making the model novel for the preliminary design of such structures. The finite element model has been validated based on available data in the literature. The coupled aerostructural analysis and the coupled-adjoint sensitivity analysis have been verified based on the cantilever wing design of A320 like aircraft. Then, the tool has been applied to optimize a strut-braced with a high aspect ratio.
