The paper presents a novel approach to modeling unsteady aerodynamic forces in response to traveling gust excitation. Time-domain convolution; autoregressive moving average; and state-space models are presented that are identified based on CFD input-output data. These models are compact and computationally efficient and reproduce the CFD response highly accurately in the subsonic flow regime. The proposed models can be straightforwardly integrated into the time-domain formulation of the aeroelastic equation of motion in response to gust excitation. They can be used for both discrete and continuous gust responses; as presented in the paper;
