撞击作用下螺压复合改性双基推进剂药片的响应
Response of Screw Extruded Composite Modified Double-base Propellant Pellets under Impact Action
摘要
Abstract
The critical values of decomposition,combustion or explosion response of screw extruded composite modified double-base (CMDB) propellant pellets occurred under impact action were investigated by a drop weight instrument and the influence rule of different mass fraction of RDX,thickness of sample and sample temperature on the critical values of response of propellant under impact action was obtained.Results show that introducing RDX into double-base propellant does not increase the sensitivity to impact stimulation of the propellant.When the mass fraction of RDX is 0-54.5 ％,with increasing the content of RDX,the sensitivity to impact stimulation of propellant pellets is gradually decreased.When the thickness of sample is 1,2 and 3 mm,with increasing the thickness of sample,the sensitivity to impact stimulation of propellant pellets is significantly decreased.Compared with the sensitivity to impact stimulation of propellant at 25 ℃,the propellant at 70 ℃ to impact stimulation is more sensitive.关键词
