摘要
从理论和实验两个方面对一种高能量、高强度发射药进行了探讨,确定了以混合硝酸酯增塑的聚醚聚氨酯作为发射药网络结构的主体。研究了发射药的基本配方,并初步测定了燃烧性能、力学性能。结果表明:聚醚聚氨酯发射药具有较高的能量(火药力高于1251kJ/kg),同时具有良好的力学性能,特别是良好的低温力学性能。对该发射药的加工方法进行了初步的摸索,用挤压成型方式制成了多孔发射药。可以预见,此类发射药会成为一类具有应用前景的高能、高强度发射药。
The high energy and high strength propellant has been discussed through theory and experiments,and its main meshwork has been established as polyether poitamine ester with mixed nitric acid ester as plasticizing agent.The basic component has been studied.The combustion and dynamoic properties of the propellant with typical component have been simply tested.The results show that the polyether poitamine ester propellant has higher energy(propellant force can be 1251 kJ/kg) and better dynamic property expecially at low temperature. The processing method of this propellant has also been studied primarily. The multiperforated propellants have been produced with extrusion method. These types propellants will be in prospect of application.
