Accurate Prediction of Panel Flutter Applicable to Supersonic or High Lift Flight: Results and Comparison to NASA Wind Tunnel Data

Avoiding flutter of an aircraft's skin is important for safe and robust operation. Traditional panel flutter prediction tools fall short for conditions where the boundary layer thickness varies. Ansys’ fluid–structure interaction (FSI) capability accurately predicts panel flutter under the most challenging conditions. Ansys simulation results will be compared to NASA supersonic wind tunnel data. The simple simulation process and surprisingly small computational requirements for accurate results will also be summarized. Prime applications for the Ansys FSI capability include next generation supersonic transports heralded by NASA's (X-59) low boom demonstrator or high lift flight conditions of subsonic aircraft.
