Burn rate of a novel boron-AN-water green solid propellant

FirePhysChem, 2022
A novel composition of green solid rocket propellant has been suggested and examined. Boron powder was chosen to serve as fuel, for its very high energetic potential, which exceeds that of other common metals, as well as that of fossil fuels.
