The development of gliding reentry vehicle is a process of small-batch and multi-batch. In order to reduce the cost of experiments and shorten the cycle of modeling of gliding reentry vehicles with similar shapes, the new method based on model migration is presented in this paper. Specifically, a method of assessing the similarity degree of the gliding reentry vehicles is explained; whether the model migration theory can be applied in the vehicle modeling depends on the degree. The aerodynamic coefficients of the base gliding reentry vehicle are partitioned by the linearity of itself, and the cluster centers of the intervals are obtained. The migration equations are given through the analysis of the relation of the cluster centers of aerodynamic coefficients of the base vehicle to the ones of the new vehicle. The advantage of the new method is verified by the simulation.
