Abstract:

Based on the aerodynamic identification technique in which the unsteady CFD is used, the unsteady aerodynamic reduced order models (ROM) are constructed- Coupled with the structural equations, the models for transonic aeroelasticity in state-space are got. A Mach number flutter trend of a typical airfoil section with a control surface is analyzed and the results obtained agree well with those with CFD/CSD direct coupling method.
