| This thesis is concerned with the development of a multidisciplinary optimization framework for the design of aircraft accounting for fluid-structure and fluid-acoustic coupling effects. The center of this framework consists of a gradient based optimization algorithm, a computational fluid dynamics method and a computer aided geometric design approach. A discrete-analytical sensitivity analysis method for coupled fluid-structure and fluid-acoustic problems is presented, featuring direct and adjoint approaches. The optimization framework is applied to two problems in aircraft design: aeroelastic optimization of wings and sonic boom minimization of complete aircraft geometries. |
