Aeroelastic Analysis and Optimization at Conceptual Design Level Using NeoCASS Suite

The present work outlines NeoCASS, the Next Generation Computational Aero-Structural Sizing Suite, developed at the Department of Aerospace Engineering of Politecnico di Milano. The computational suite is completely developed within MATLAB c ⃝ environment and aims at the structural sizing and aeroelastic analysis and optimization at the Aircraft Conceptual Design stage. NeoCASS is part of a more complex multidisciplinary procedure able to completely tackle the conceptual design starting from a simple parametric geometry description and encompassing issues related to aerodynamics, flight performances, stability and control, propulsion and finally strucures/aeroelasticity. The whole design tool has been developed in the frame of SimSAC (Simulating Aircraft Stability And Control Characteristics for Use in Conceptual Design) project, funded by EU in the context of 6th framework Program (www.simsacdesign.eu). The paper is mainly focused on the recent developments of NeoCASS, such as the modifications of Doublet Lattice Method to include in-plane effects and the implementation of the flutter constraint to be included in the multidisciplinary design optimization.
