In order to establish an accurate UAV taxiing model, the tricycle type UAV with high aspect ratio was chosen as the research object, and the dynamic analysis about the ground taxiing is carried out. Aerodynamic model was established according to the wind tunnel data and air dynamics equation, thrust model was set up according to the engine parameters, the landing gear model is established according to the gear mechanical properties and the magic formula is used to establish tire friction model. In the Matlab/Simulink environment, a digital model was built, and the simulation verification was carried out by using the differential algorithm method of Runge-Kutta. The simulation results show that the ground taxiing model can accurately reflect the force of the UAV on the ground, and it proves that the modeling method is feasible and effective.
