The paper describes the new optimization feature of the NeoCASS suite, which allows to size a general wing box structure considering the aeroelastic effects. During the conceptual phase of the design the aircraft is represented by a stick model with steady/unsteady aerodynamics (VLM/DLM), a link between the stiffness and mass matrices of the 1D elements and the 3D world is provided by a meta-model of the wing box. The optimization is performed considering the maneuvers which define the load envelope of the aircraft compliant with CS25 regulation, analytical constraints on failure and buckling of the components are imposed.

Abstract
The paper describes the new optimization feature of the NeoCASS suite, which allows to size a general wing box structure considering the aeroelastic effects. During the conceptual phase of the design the aircraft is represented by a stick model with steady/unsteady aerodynamics (VLM/DLM), a link between the stiffness and mass matrices of the 1D elements and the 3D world is provided by a meta-model of the wing box. The optimization is performed considering the maneuvers which define the load envelope of the aircraft compliant with CS25 regulation, analytical constraints on failure and buckling of the components are imposed.| File | Dimensione | Formato | |
