Wing Bending-Torsion Flutter Predictions
This form calculates the frequency solution for a 2 DoF bending/torsion model of a straight, high aspect ratio wing.The geometry of the wing along with its natural frequency and mass components is required so that airflow forced frequency may be computed. The solution may be purely real, indicating a stable oscillating solutionor a complex root indicating an unstable solution.
