Zusammenfassung:
A simple and efficient algorithm for robust flutter analysis is presented. First, a general Linear Fractional Transformation (LFT) formulation of the µ-k method is provided. The new formulation establishes a close connection between µ-k flutter analysis and traditional frequency-domain flutter analysis, which is used to formulate an efficient algorithm for computation of robust flutter boundaries. The proposed method is successfully applied to a NASTRAN/ZAERO F-16 sample test case, showing that standard tools for structural dynamics and unsteady aerodynamics can be used to perform robust flutter analysis with only modest additional modeling.
