要約

Novel spherical grain-binding, high-burning-rate propellant is a kind of compound structure propellant (called a consolidated propellant) that is prepared using a spherical granular propellant (spherical propellant grains) as the dispersed phase and a colloidal binder as the continuous phase. The effects of composition, particle-size, and morphology of spherical propellant grains on the combustion performance of propellants were each investigated. The results show that the burning rate of the propellant decreases with the increase of the burning rate of spherical propellant grains. The greater the difference in burning rate between the spherical propellant grains and the binder, the higher the burning rate of the propellant will be. The burning rate of the consolidated propellant increases with a decrease in particle size. When compared with that of propellants prepared with smooth-faced spherical propellant grains, the burning rate of propellants prepared with shaggy spherical propellant grains is much higher; however, combustion can become less stable.
