A type of high-performance fuel-rich propellant for the unchoked ducted rocket has been developed. The burning rates of the fuel-rich propellant are greater then 2mm/s at 0.5MPa, the greatest one is up to 4. 05mm/s. The burning-rate exponent is greater than 0.5, the highest one reaches 0.58. The fuel-rich propellant grain can combust steadily in the gas generator at 0.226MPa. The uniaxial mechanical properties and the processability of the fuel-rich propellant are good.
