Aeroelastic Optimization of High Aspect Ratio Wings for Environmentally Friendly Aircraft

The paper deals with the aeroelastic optimization of a high aspect ratio wing, in the framework of the EU funded project CS2-U-HARWARD, aiming at the use of innovative aerodynamic and aeroelastic designs in a multi-fidelity multi-disciplinary optimal design approach to facilitate the development of high and ultra-high aspect ratio wings for medium and large transport aircraft. The optimization tool here adopted, called NeOpt represents a new module of the well know NeoCASS suite, an open source founded by POLIMI project for quick analysis and optimization of aerostructures ad conceptual and preliminary levels. The suite is linked to a dedicated module developed by IBK for the estimation of aircraft emissions so to quick assess the optimized aerostructural configurations in terms of global impact targets. Details of the adopted tools as well as the preliminary results obtained are reported in the paper.
