Questo lavoro presenta le analisi e le prove eseguite su un modello aeroelastico che rappresenta un velivolo convenzionale da trasporto passeggeri. Le attività ed i risultati raccolti sono nell’ambito del progetto di soppressione di flutter per mezzo di tecnologie di controllo attivo (AFS) in collaborazione tra la University of Washington e il Politecnico di Milano. L’obiettivo del progetto è l’installazione e la validazione sperimentale di un modello aeroelastico accurato per studiare e validare tecnologie per la soppressione attiva del flutter. Questo lavoro include analisi sperimentali e numeriche e le relative correlazioni, nonché i risultati dei test effettuati nell’ultima sessione di prove in galleria del vento presso il Politecnico di Milano (GVPM), durante l’ultima settimana di gennaio 2020 con il modello X-DIA, in configurazioni ad anello aperto e chiuso. Infine, viene riportato quanto appreso in base ai risultati ottenuti e i possibili lavori ed implementazioni future.

Abstract
This work presents the analyses and tests carried out on an aeroelastic model representing a conventional passenger transport aircraft. The activities and results collected are part of the Active Flutter Suppression (AFS) project in cooperation between University of Washington and Politecnico di Milano. The aim of the project is the setup and the experimental validation of an accurate aeroelastic model to investigate and validate technologies for active flutter suppression. This work includes experimental and numerical analyses and the related correlations as well as the results of the tests undertaken in the last wind tunnel session in the Galleria del Vento Politecnico di Milano (GVPM), during the last week of January 2020 with the X-DIA model, in open and closed loop configurations. Finally, the lessons learned based on the obtained results and the possible future improvements and implementations are also reported.File | Dimensione | Formato | |
