000021366 520__ $$2eng$$aAircraft developers and builders commonly design and produce potentially unstable aeroelastic systems. Detailed and reliable knowledge of real dynamic properties of the system has a crucial importance to safety requirements compliance. Dynamic stability margins of an aeroelastic system are identified analytically in the first step and finally verified experimentally. Dynamic response analysis of a real aeroelastic system under operational conditions represents key approach to the experimental study of the systems stability margins in a complex experimental verification process. Operational modal parameters in the form of modal frequencies, modal damping and mode shapes are identified on each stage of operational parameters combination series. Modal damping parameter evolution is of special interest during the testing. The paper presents a technique of combined approaches to the dynamic response analysis during wind tunnel dynamic stability margins testing of an aeroelastic demonstrator.
