The experimental stand for the flutter analysis was described. In this stand one can measure simultaneously unsteady aerodynamic force and moment with arbitrary combinations of bending and torsion motions of airfoil cascades in the subsonic flow. The cascade is composed of nine blades, four of them are vibrating. Unsteady flow effects have been investigated for subsonic flow in a compressor cascade. Specifically, experimental forced bending and torsion vibration were performed. The aerodynamic work coefficient of bending and torsional cascade vibrations for different interblade phase angles, Strouhal Numbers, and the incidence angles were shown.
