Abstract

Modal identification was performed on flight test data using the Curve Fitting Frequency Domain Decomposition (CFDD) method. The emphasis is to identify aeroelastic modes rather than rigid body modes. Consequently, the aeroelastic short period mode was identified in addition to several higher frequency aeroelastic modes. All of the modes identified reflect complex-valued aeroelastic modes, as opposed to real-valued dry structural modes. The following flights were used for identification: Sköll Flight 3: 20 m/s flight condition; Sköll Flight 4: 30 m/s flight condition.
