Abstract
To promote the resource utilization of retired HTPB propellants,composite gel explosives were prepared by com-pounding them with energetic gels:the three-component propellant-containing composite explosive 1-PxDyϕz,the quaternary propellant-containing composite explosive 2-Px Dyϕz that contains 9%RDX,the propellant-containing composite explosive 3-Px Dyϕz that contains 15%RDX,and the propellant-containing composite explosive 4-Px Dyϕz that contains 20%HMX.(x represents the content of propellant P,x=30%,40%,50%,y is particle size,y=5,10,15 mm;z denotes the charge size,z=40,50,65 mm).Tests on detonation velocity,witness plate damage,and underwater explosion energy were conducted to in-vestigate the energy characteristics of these composite gel explosives with varying propellant content,particle size,and charge diameter.The results indicate that an increase in the propellant content in 1-Px Dyϕz and 2-Px Dyϕz composite explosives reduc-es the detonation velocity and brisance of the composite explosives,whereas increasing the propellant content in 3-Px Dyϕz and 4-Px Dyϕz increases both detonation velocity and brisance.The decrease in propellant particle size from 1-Px Dyϕz to 4-Px Dyϕz contributes to the increase of detonation velocity and brisance,and the increase in charge diameter significantly increases the damage capability.Results of underwater explosion tests show that an increase of propellant content in 1-Px Dyϕz and 2-Px Dyϕz reduces the total underwater energy output,while 3-Px Dyϕz has a relatively constant total energy with an increase in propellant content,and 4-Px Dyϕz has an increasing total underwater energy with an increased of propellant content.Additionally,the to-tal underwater energy from 1-Px Dyϕz to 4-Px Dyϕz increases with the decrease of propellant particle size.关键词
