摘要

A comparison of robust flutter analyses within the μ framework is presented. The chosen test bed is the typical section with unsteady aerodynamic loads, which enables basic modeling features to be captured and so extend the gained knowledge to practical problems treated with modern techniques. The two main approaches to pose the LFT problem are investigated and features such as numerical accuracy and physical uncertainty description are assessed. A criterion is proposed to correlate the families of plants originated by the uncertainty description of the aerodynamic operator when different approximation algorithms are employed.
