摘要:
针对传统钝感、包覆发射药设计方法存在的固有局限,基于硝化纤维素分子特点和能量释放过程控制方法,提出了发射药表层分子(基团)裁剪方法的概念与实现方法,采用该方法制备的发射药称之为梯度硝基发射药(nitro gradiently distributed propellant, NGDP)。该类发射药是将表层中的硝酸酯基梯度水解脱除,实现发射药表层硝(酸酯)基梯度增加,从而使得发射药燃速渐进增加,与钝感发射药和包覆发射药通过增加“惰性”组分实现燃速的渐进增加的方法相比具有本质区别。最后,进一步介绍了梯度硝基发射药在武器应用中所具有的优越贮存稳定性、内弹道性能和低发射有害现象的特征,证明了所提出新方法的先进性。
Abstract:
In view of the inherent limitations of traditional gun propellant with deterring and coating method, based on the molecular characteristics of nitrocellulose and the basic principle of energy release process control method, the concept and method of surface molecule (functional group) tailoring of propellant were proposed in this paper. The propellant prepared by this method is called nitro gradiently distributed propellant (NGDP). The forming process of the propellants is that, the nitrate esters in the surface layer are hydrolyzed and removed by certain ways, the nitrate esters finally gradiently distribute in the surface layer of propellant. This ideal structure realizes the burning progressivity during propellant burning. It is essentially different with the deterred propellant and coated propellant, which achieves a progressive increase in burning rate by adding deterring agents. Finally, this paper further introduces the characteristics of the NGDP,including its superior storage stability, internal ballistic performance and low emission of harmful phenomena in weapon applications, which proves the advanced nature of the proposed new tailoring method.
