摘要
采用DSC-TG、密闭爆发器、中止燃烧试验装置,研究了含N-脒基脲二硝酰胺盐(FOX-12)的硝胺发射药的热分解和燃烧特性。结果表明:该硝胺发射药中的NC-NG体系和FOX-12一起开始分解,加入FOX-12使硝胺发射药的燃速压力指数降低,其值小于1,随着FOX-12含量的增加,硝胺发射药的压力指数在低压段(10～20 MPa)降低幅度大于中高压段(40～240 MPa)的幅度。
The thermal decomposition and combustion characteristics of nitramine propellants containing N-guanylurea-dinitramide （FOX-12） were studied by DSC-TG,a closed bomb and an interrupted-burning testing instrument. The results show that NC-NG and FOX-12 in the nitramine propellant begin to decompose simultaneously. Adding FOX-12 makes the pressure exponent of the nitramine propellant reduce to less than 1. With the rising of the FOX-12 content,the decline extent of the pressure exponent in the low pressure of 10 -20 MPa is larger than that in high pressure range of 40 -420 MPa.
