Optimization of Forming Processes for Gelled Propellant Manufacturing

This chapter presents the basic methodologies for quality control and productivity improvement in the processes used for manufacturing of energetic materials such as gelled (colloidal) propellants, in which the electronic control systems are constrained by the severe safety requirements associated with on-process self-burning risks. The required measuring devices for data acquisition and management, the testing techniques for rheological characterization and the relationship among the main process and material parameters are the main issues introduced in this chapter, with the purpose of establishing the routines needed for an appropriate quality control of gelled propellant production. This work is focused on manufacturing processes such as batch mixing and ram extrusion. A similar methodology could be also followed for screw extrusion, in which both mixing and extrusion stages are carried out by the same equipment.
