Modeling limit cycle oscillations for an NLR 7301 airfoil aeroelastic configuration including correlation with experiment

Conference Paper

Presented is an investigation into the modeling of limit cycle oscillation (LCO) behavior of an experimental transonic airfoil aeroelastic configuration using a frequency-domain harmonic-balance (HB) computational fluid dynamic (CFD) approach. The aeroelastic model has a single structural degree-of-freedom in pitch. Wind-tunnel wall interference effects are included in the CFD model. A wind-tunnel resonance is observed near the flutter onset and LCO conditions.
