Flutter analysis of controlled resized ACFA-BWB configuration
TL;DRAbstract
The presented report contains the result of the flutter analysis of the resized ACFA-BWB a/c. The resizing was done by TUM-LLB for the a/c with and without load. Compared to the flutter analysis in WP1 the aeroelastic stability envelope was adapted to available design speeds delivered by Airbus-F. A typical flutter mechanism was found after the resizing process, though the ACFA-BWB is found flutter free within the aeroelastic stability envelope investigated on selected mass configurations. Additionally a flutter analysis using CFD-based generalized aerodynamic forces calculated by TUM-AER for a selected Mach number was performed. The flutter analysis showed also that flutter does not occur within the aeroelastic stability envelope for all ACFA-BWB versions (V8 and V9) and mass configurations (MC01-MC05). The report corresponds to the deliverable report D4.7 of the EC funded ACFA2020 project
