| Abstract: | Based on the analysis of the typical basic movements and aerodynamic of post-stall maneuvers,the idea of modeling is given,and a simple state-space model of unsteady aerodynamic for aircraft in rapid pitch oscillation is established. The predict results of the model achieve good agreement with experimental data and show that the model is rational and feasible. |
