Abstract:

Combustion characteristics of Boron-based fuel-rich propellant was studied by strand burner method and gas generator method; and the influences of some factors, such as Boron agglomeration, content and grading of AP, content of HMX, kind and content of catalysts, also were studied. The results show that the combustion pressure limit of boron-based fuel-rich propellant can be reduced to 0.2MPa, and the pressure index also can be improved to 0.46.
