Surface treatment and agglomeration distinctly improve the processing property of boron-fuel-rich HTPB propellants by rendering the boron powder unreactive or compatible with HTPB and optimizing the particle size distribution of solid filler.

In order to study the effect of agglomerated boron powder on the energy release and burning rate characteristics of boron-based fuel-rich solid propellant,the physical and mathematical combustion models of this propellant were established based on the experimental analyses and BDP model.

Study on burning surface sedimentary deposit of boron-based fuel-rich propellant;

Affecting factors on primary combustion ejection efficiency of boron-based fuel-rich propellant;

Improved timing device of burning rate test set for boron-based fuel-rich propellant;

Effects of AP content and granularity gradation on pressure exponent of boron-based fuel-rich propellant;

In-depth researches on primary combustion of boron-based fuel-rich propellant containing 30% boron were completed on the base of experiments and theoretical analysis, establishing a basis for application on item of missiles.
