Different ways were tried to enhance the energy of double base propellant made by using screw extrusion,and the effect of engine structure and loading condition on specific impulse was studied as well.The experimental results show that the specific impulse can exceed 2354N·s/kg under the reasonal combination of some important factors such as proper propellant formulation,the engine stucture and loading condition.
