Research progress of processing aids for high energetic solid propellants

The research progress of the aids for the improvement of processing properties in high energetic solid propellants was summarized. Research and application of the processing aids were introduced according to the method to improve the processing performance of the propellant slurry, such as diluting the slurry, extending of the pot life, improvement the fluidity of the slurry, etc. The aids which could improve the fluidity of the particles and the mechanical properties of the propellant at the same time were much reported in recent years and were introduced emphatically. Some views on the further study of the multi-functional aids for high energetic solid propellants were presented.
