Deutsche Forschungsgemeinschaft (DFG) - Project number 133733460
This project considers the computer-aided modeling, analysis and evaluation of the structural dynamics of the CRC reference aircraft configurations taking into account the fluid-structure interaction. One focus is the realisability of the Coanda system – with its suction and blowing system and its trailing edge flap – in light-weight design and the evaluation of its effectiveness under pulsed blowing using CFD-CSM models. The numerical models and design shall be validated against the NWB wind tunnel experiment results. Second focus is on the critical flutter issues of the complete aircraft configuration with wing-fuselage T-tail modes. Here, reduced order modelling enables the analysis of the flutter properties in slow flight with active Coanda system. Additionally, the flight envelope at cruise conditions is verified. The use of the pulsed and spanwise variable blowing to affect the flutter properties is a new link between investigations at the Coanda system level and those at the complete configuration level.
