摘要
将RDX、铝粉、催化剂等用硝化棉包覆,制成复合球形药,然后用这种复合球形药制备出改性双基推进剂,测试了这种推进剂的力学性能和燃烧性能。结果表明,采用复合球形药制备的改性双基推进剂比用双基球形药制备的改性双基推进剂的力学性能大幅度提高,低温断裂延伸率从7.84%提高到26.86%,高温最大拉伸强度提高了0.97倍,燃速压强指数从0.38降低到0.30。
Al powder,RDX and catalysts was coated by nitrocellulose and formed composite spherical green powder. The modified double-based propellant product was produced by the composite spherical green powder. The effects of the composite spherical green powder on mechanical and combustion properties of formed propellant were studied. Results show that their mechanical properties are much better than that of double-based spherical green powder made propellant. Their low temperature elongation at break from is increased from 7.84% to 26.86%,the max ensile strength at high temperature is close to double increase,and the temperature pressure index is decreased from 0.38 to 0.30.
