Abstract

An forced motion experiment on earoelastic stability is performed within a Mach number domain of 0:7 < M < 1:2. The panel structure is de ected in its first bending mode shape. The objective is to obtain the aerodynamic response over an extensive range of amplitudes and frequencies of panel motions. Beside the measurement of the panel deformation by a stereo camera marker tracking system, the ow response is measured by high sensitive miniature pressure transducers. Results of pressure coefficient distribution measurements and deformation measurements are presented. Concluding, first preliminary comparisons of experimental data and numerical results gained within the project are are discussed.
