Abstract
A testing and data analysis procedures is presented to determine the different aeroelastic aspects in different flow regimes. The procedure provide significant differences of nonlinear response characteristics between high-speed civil transport flexible semispan model (FSM) and subsonic/transonic flight regimes. The physics and response characteristics of an aeroelastic systems over different operational regimes were also determined during the study. It was observed that the nonlinear responses of subsonic and transonic regimes were different from each other. The proposed testing method also can be used to analyze the acceleration data obtained from the sweep excitations in the subsonic and transonic tunnel conditions. The FSM experiment was carried out at the NASA Langley Research Center.
