This article proposes a scheme to estimate the aerodynamic derivatives of aircraft using a wind tunnel dynamic test rig system. A five-degree-of-freedom (DOF) rig system has been used to simulate near free flight manoeuvres inside the wind tunnel by exciting a scaled down model aircraft through various types of control surface deflections. A mathematical model that incorporates five DOF in aircraft motion has been developed. The five DOF equations of motion of the rig system are formulated using a vector and matrix approach. The simulated flight data, generated from a five DOF mathematical model, has been used to estimate the aerodynamic parameters of the aircraft. The maximum likelihood method has been used to achieve close estimates of the parameters by minimizing the error between simulated and computed response.
