EBF3GLWingOpt: A Framework for Multidisciplinary Design Optimization of Wings Using SpaRibs
… structural weight saving. The local panel model is extracted from the global finite element model. The boundary conditions are defined on the edges of local panels using the displacement fields obtained from the global model analysis. The local panels are optimized to satisfy stress and …

A CFD framework for aeroelastic gust load calculations
… The latter was represented by a beam stick model using Timoshenko beam theory in Elementaltextsuperscript{textregistered}'s structural module. The case under consideration was the NASA Common Research Model (CRM) flying at Ma = 0.86 with a 30 ft gust applied over the aircraft. Key …

Towards a hybrid CFD platform for investigating aircraft trailing vortices
… specific application area under consideration is modeling the trailing vortices shed from the wings of aircraft under transonic flight conditions. For this purpose, the Elemental® finite volume code is employed in the vicinity of the aircraft, while the Essense finite difference software is …

Use of hybrid airfoil design in icing wind tunnel tests of large scale swept wings
… testing difficult. Hybrid or truncated airfoil models use full-scale leading edges with redesigned aft sections to provide test articles with much reduced model chord and therefore tunnel blockage allowing effectively full-scale icing testing on very large wings. This thesis presents research …

Multidisciplinary Optimization and Damage Tolerance of Stiffened Structures
… For the optimization of a complex wing, a common strategy is to divide the optimization procedure into two subsystems: the global wing optimization which optimizes the geometry of spars, ribs and wing skins; and the local panel optimization which optimizes the design variables of local …
