A KIND OF SCREW EXTRUSION MODERATE-ENERGY MODIFIED DOUBLE BASE PROPELLANT WITH LOW BURNING RATE

摘要

A new modified double base propellant with moderate energy and low burning rate is successfully prepared by the screw extrusion technology. Burning rate of the propellant can be modulated from 7mm/s to 8mm/s at 5MPa, and the plateau effect is also obtained over a wide range of pressure of 3～7MPa.While its measured value of specific impulse is 220s within 3～ 5MPa.
