Abstract

Forming process is a key process in the manufacturing of propellant. In order to get insight into the flow behaviour during the forming process of 7-hole single-base propellants, this study conducted a dynamics simulation on the forming process based on fluid mechanics methods and finite element methods. The dynamic model of the 7-hole propellant forming process was solved using the PolyFlow finite element software, and the flow behaviour of the propellant inside the die is analysed and the forming quality is evaluated. Results show that the material flow in forming part exhibits a stable flow distribution, which is beneficial for the formation of the 7-hole propellant.
