ABSTRACT
A new, dynamic two degrees-of-freedom (2DOF) oscillation rig, SLUK, which implements joint heave and angular harmonious oscillations of an aircraft model, was developed at TsAGI. The rotary and unsteady derivatives of the pitching moment coefficient and their sum are obtained experimentally for a passenger aircraft in a wide range of angles of attack. The values of the unsteady derivative obtained experimentally are shown to be in good agreement with its evaluations determined as the difference between the experimentally obtained values of the sum of the rotary and unsteady derivatives and the rotary derivative of the pitch moment coefficient.
