A numerical method combining Lattice Boltzmann and Large Eddy Simulation (LBM-LES) is used to simulate the wind field of the unsimplified carrier model under different wind speeds and wind angles. By analyzing the distribution characteristics of the wind field on the ideal landing trajectory, it is found that the dimensionless time-averaged wind speed has a similar distribution pattern and magnitude along the trajectory under the same wind angle and different wind speed conditions. The vertical component has a typical "rooster tail" distribution, with the peak of the sinking airflow being about 10% of the incoming velocity. For the same incoming speed and different wind angles, the influence of the wake on the landing trajectory during port wind is significantly larger than that of the starboard wind. In addition, the vertical velocity on the landing trajectory is mainly sinking in port winds and both sinking and rising in starboard winds, but predominantly upwelling.
