Abstract

The new dynamic test rig is designed in TsAGI to investigate the aerodynamic damping derivatives of the aircraft models in wind tunnels at high subsonic and transonic speeds. The action of the rig is based on the free oscillations method with the use of elastic elements. The dynamic test rig is equipped with the five component strain gage balance. Both direct and cross aerodynamic damping derivatives can be measured. The comparison of the results for the Standard Dynamic Model (SDM) is presented.
