Coupled adjoint aerostructural optimization framework for preliminary aircraft design
Coupled adjoint aerostructural optimization framework for preliminary aircraft design
In order to explore and exploit the full potential of aircraft design, the aircraft must be designed as it is, a coupled system. Previous works have laid the foundation for this path by developing a tool for wing aerostructural optimization. In this work, the tool is extended to include the horizontal stabilizer. An aeroelastic optimization is performed to validate the methods used to estimate weight and sensitivities, while an aerostructural optimization is performed to exhibit the performance of the tool in its current state. The aerostructural optimization shows both improvements in the configuration, such as an 8.2% reduction in fuel weight, while also exhibiting the additional complexities and requirements for the optimization framework when considering more than just the wing in the aircraft system

Abstract
In order to explore and exploit the full potential of aircraft design, the aircraft must be designed as it is, a coupled system. Previous works have laid the foundation for this path by developing a tool for wing aerostructural optimization. In this work, the tool is extended to include the horizontal stabilizer. An aeroelastic optimization is performed to validate the methods used to estimate weight and sensitivities, while an aerostructural optimization is performed to exhibit the performance of the tool in its current state. The aerostructural optimization shows both improvements in the configuration, such as an 8.2% reduction in fuel weight, while also exhibiting the additional complexities and requirements for the optimization framework when considering more than just the wing in the aircraft system
