Effect of Restraint Conditions on Shock Pressure of Booster

WANG Zuoshan, LIU Yucun, ZHANG Jinglin, ZHANG Baomin(North China Institute, Taiyuan, 030051, China)  
The shock pressure of booster HMX/F2641 with smaller charge diameter was determined under three sorts of restraint conditions through manganin manometric method, and the test results were discussed according to shock kinetics. The practical density of explosive samples used in the experiment was 90% of the theory density value. The effect of restraint condition on shock pressure under smaller charge diameter tends to increase following the increasing of impedance, but with less amplitude variation for charge diameter between 3.0 mm and 5.0 mm and wider amplitude variation for 1.5 mm charge diameter.
