Robust Flutter Analysis Considering Control Surface Aerodynamic Uncertainty

Abstract

AbstractTo reduce the conservation of robust flutter analysis results, only the uncertainty of control surface unsteady aerodynamic was modeled. The \(\mu - k\) approach was used to compute the robust flutter speed. The results indicate that robust flutter speed considering only the control surfaces unsteady aerodynamic is 716% less than entire surface case, also show that the approach for robust flutter analysis is applicable to multiple flutter modes in engineering practice.KeywordsRobust flutterControl surfaceUnsteady aerodynamicUncertaintyStructure singular value
