The Phase I effort provides an evaluation of variations of the no-impeller, no-blade propellant mixing approach. The assessment of this technology, specific trade studies of the incorporation of the technology into the propellant manufacturing process, and the accompanying laboratory evaluations demonstrate the feasibility of using this technology to replace the legacy methods for producing substantial quantities of gas generator propellant. In addition, during the Phase I Option the equipment and process designs developed in Phase I for vibration mixing, both mix-in-case and continuous mixing, are built and tested to demonstrate and validate the original designs to a TRL 4 designation.
