Reduced order model of a blended wing body aircraft configuration

Abstract

This paper describes the full development process of a numerical simulation model for the ACFA2020 (Active Control for Flexible 2020 Aircraft) blended wing body (BWB) con¦guration. Its requirements are the prediction of aeroelastic and §ight dynamic response in time domain, with relatively small model order. Further, the model had to be parameterized with regard to multiple fuel ¦lling conditions, as well as §ight conditions. High e¨orts have been conducted in high-order aerodynamic analysis, for subsonic and transonic regime, by several project partners. The integration of the unsteady aerodynamic databases was one of the key issues in aeroelastic modeling.
