Abstract The grain, the structure, the flow field and the acoustic field are critical to solid rocket motor (SRM) design, where engineers are urging for a typical SRM with high efficiency and could realize the adjustment of the parameters within limits. Aiming at evaluating the quality characteristics of the SRM roughly and getting the multi-physics fields used for process simulation rapidly under the burning regression, utilising the Creo platform, this paper proposed a standard process for the parametric design of a solid rocket motor and tracking the burning regression, applying the concept of top-down modelling and the method of feature modelling respectively. Additionally, this paper has conducted the secondary development of Creo, the function of modifying parameters, regenerating models and exporting files was encapsulated in programs, avoiding the complexity and misoperation of manual operation.
