PROPELLANT FOR ROCKET PROPULSION SYSTEM CAPABLE OF IMPROVING TENSILE DEFORMABILITY OF SOLID PROPELLANT

摘要

PURPOSE: A propellant for a rocket propulsion system is provided to improve tensile deformability of a solid propellant efficiently by relieving concentration of stress around solid filler particles. CONSTITUTION: The propellant for a rocket propulsion system comprises a solid filler formed of primary particles and secondary particles having sizes less than those of primary particles, wherein the content of the primary particles is greater than 80% and less than 100% based on the total weight of the solid filler. Particularly, the ratio of the average diameter of the primary particles to that of the secondary particles ranges from 25 to 85. The primary particles may be formed of at least two groups of particles having different sizes.
