| Abstract: |
| The main equations for computing the unsteady aerodynamics of the aircraft undergoing the travelling gust are derived. Research and simulation on a specific example aircraft are performed, the results indicate that the modeling technique of the aircraft unsteady aerodynamics is correct, and it can meet the requirements due to the head-on and tail-on travelling gusts. |
