This paper adopts the nonlinear regression method to establish the unsteady aerodynamic state space model and neural network model at large angle of attack. And the results show that the errors of the two models are less than 10-5. It provides a new multi-disciplinary improvement idea for the unsteady aerodynamic modeling of aircraft at high angle of attack.
