Abstract
A smokeless high-energy solid propellant composition, which contains a bismuth-based compound as a combustion improver and exhibits a low pressure exponent, and a method of preparing the same are provided. The propellant composition contains the bismuth-based compound, thus ensuring preparation processability of the propellant, especially pot-life, and thereby a propellant curing system can be changed thus ensuring reliability of the propellant preparation processability, unlike temperature control and curing inhibition catalyst addition methods published to date. This composition advantageously exhibits a low pressure exponent.
