摘要:
为了了解含RDX的高固含量改性双基（CMDB）推进剂的流变性能，采用转矩流变仪研究了螺杆转速、机体温度、口模直径、口模长径比以及RDX含量对CMDB推进剂(代料或实料)流变性能的影响。结果表明：CMDB推进剂代料表观黏度会随着螺杆转速的增加、药浆温度的升高、口模长径比的增大而减小，随口模直径的增加而小幅度增加；CMDB推进剂表观黏度随RDX含量增加而减小，且随着螺杆转速的增加，表观黏度降低趋势更加明显。
Abstract:
In order to understand the rheological properties of composite modified double base (CMDB) propellants with high solids content of RDX, screw speed, equipment temperature, die diameter, length to diameter ratio and RDX content on rheological properties of CMDB propellants were studied by a torque rheometer. The results show that the apparent viscosity of propellant substitute samples decreases as raising the screw speed, slurry temperature and ratio of length to diameter of the die, and slightly increases with the increase of the diameter of the die. In addition, the apparent viscosity of CMDB propellant decreases with the increase of RDX content, and this trend is more obvious when the screw speed increases.
