Abstract
The influence of solid propellant on warhead damage effect was studied by these quantitative parameters including lead cylinder compression value,lead block volume,shock wave overpressure and impulse. Influencing factors that effect lead cylinder compression value of warhead charge/propellant system was also discussed. The results show that four kinds of propellants all could enhance lead cylinder compression value of warhead charge/propellant system in different degrees. Contribution to lead cylinder compression value of warhead charge/ propellant system by four groups HTPB propellant is more than that by three groups HTPB propellant ( HTPB-3). Increased percentage of lead block volume is 81.4% and 54% ,respectively. When scaled distance ranges from 3.5 m· kg-1/3 to 12.5 m ? Kg-1/3,HTPB-3 contributes to shock wave overpressure TNT equivalence and impulse TNT equivalence of 1 kg PBXN/0.6 kg HTPB-3 system by an increase of 18.7% and 19.7%,respectively.关键词
