ABSTRACT

A description of a modified test bench and a test model for performing ground resonance experiments and for investigating flutter when reproducing aerodynamic forces by means of electromechanical simulation is presented. The test bench function is also the determination of stability boundaries for the "elastic model—automatic control system" contour. The reliability assessment of artificial flow by autonomous complex measurements and comparison of experimental and computed data of self-oscillation boundaries have been carried out for the first time. Examples of the investigation results are presented.
