Basic Rheology and Its Application to Nitrocellulose Propellant Processing by Screw Mix-Extruders

Abstract

This document is intended to provide an introductory review of the rheology of propellant doughs and the propellant mixing process. The fundamental rheological quantities describing the flow of propellant doughs in mixing and extrusion are described, and the molecular factors affecting flow are discussed. Batch mixing is analysed in terms of the fundamental parameters which have been introduced, and a method of analysing screw mix-extrusion in a similar way is suggested.
