The Continuous Mixing Process of Composite Solid Propellant Slurry by an Artificial Muscle Actuator

Abstract

In this study, the mixing of a composite solid propellant production was investigated. Usually, propellant is mixed in batches during multi-batch processing. In this work, we demonstrated that continuous mixing with a peristaltic pump containing an artificial muscle actuator could replace batch mixing, resulting in a safe, efficient manufacturing process. In continuous mixing systems, it is important to consider the correlation between the degree of mixing of the propellant slurry and the operational variables of the pump, and we focused on the air feed pressure variable.
