Abstract: A study for the leveling properties of the slurries of HTPB and CTPB composite solid propellants has been carried out. The results show that the levelness of propellant face and the slurry yield value are very closely related.The lower yield value corresponds to the easy face leveling and high yield value is related to the face rugged or heap up correspondence. In addition, the results also show that the flawless of grain construction is related to the leveling properties.This paper suggests that the slurry yield value measured experimentally can be taken as a criterion of the propellant leveling.
