In order to study the influence of microburst on the ballistic characteristics of rockets, an engineering model was established by using the vortex ring method based on the basic principle of hydrodynamics and the theory of the exterior ballistic. The wind field model is combined with the six-degree-of-freedom rigid-body ballistic model of rockets. This study examined a kind of empennage-rocket whose flight process was influenced by a microburst. The simulation results show that the microburst model based on the vortex method is simple and the three-dimensional characteristics are good, which can describe the main wind field characteristics of the microburst in a certain extent. Meanwhile, the microburst affects the ballistic characteristics of rockets such as the trajectory, velocity and angular motion. The extent of the effect is concerned with the vertical wind velocity along the central axis and the vortex ring radius of the microburst model.
